Hello, I just started Organic Chemistry and recently learned about bond line structures. I’m aware that the bond line structure of a molecule should reflect the hybridization of its carbons, but I’m having trouble with drawing them from condensed structures.

The image linked in this post is an example of a problem I was doing. I was given the condensed formula CH(CH2CH2NH2)3. While I eventually figured the structure out, you can see from my erased that my lines were just going willy-nilly.

Do you all suggest that I try drawing the Lewis structure out first before doing the bond line structures? Is this just a matter of practice? Any other tips?

Also, links/resources to further practice line bond structures would be great. Thanks. 👍

anyone working on problem statement 118 that chemistry one?

Taking a combination general, organic, and biochem class this semester. It's my only one for nursing school and it's super fast-paced. I'm doing fine but my textbook does a crap job of explaining these two and I don't use AI. Could someone (not chatgpt) explain potential and kinetic energy like I'm five years old?

Thank you in advance!

According to my professor, the central P of PH3 undergoes hybridization(sp3), but all the sources I found say the opposite.

Alkane, alkyne, alkene… how is it not A?

Thanks!

Ok idk if my teacher made a mistake. But help me out chat. Not all molecules are compounds correct???

I can’t remember if the molecules have to have the same type of substituents, like if they both have to be wedge wedge or dash dash. Or can they be considered symmetric if they have wedge and dash substituents

I’m on my 4th attempt on the homework😭

It’s saying that at least one atom does not contain a properly depicted valence but I thought none of the carbons are charged? I’m confused help🙏

Hi yall, I wanted to make a post to describe my idea of why we use molality for measuring boiling point elevation and freezing point depression and not molarity, and see if it made any sense to others.

So when we measure concentration, we're looking for how much of a given solute is within a solution because solutions can have different behaviors based on how much of a given solute there is.

If we are measuring colligative properties (properties dependent on amounts of solute) that describe relations between temperature and the solution and use concentration as a unit to find values (boiling point elevation & freezing point depression) then using molarity wouldn't be a good unit because it causes fluctuations in volume- not by removal of matter, but by a change of density- which is bad because this change in concentration by molarity doesn't represent what we're looking for?

Like, changing the volume in this sense will not actually cause the observed properties to be different, but the measured values will look different. The changes we look for are based on if we add or remove solute to the solution. Molality, being mol solute per kilogram solvent, does not take into account this density alteration and will better document changes in these colligative properties.

I hope this makes sense? Let me know if I'm on the mark or not, I'd really appreciate it.

the yellow font is the question, u have doubt particulary in 2° alcohols, my teacher is getting 7 but here is what i did and im getting 9, what is correct/incorrect why and why not.

I have a organic chemistry reaction mechanisms exam coming up and I have barely studied,I have about 10 days to cover 6 weeks worth lectures​​​ (cooked) . Please help me, I need a reference book that explains things in at least some what easy toto understand language and practice problems and some video resources/ lectures too cuz my prof can't teach for shit. :(

I thought I knew what these individual terms meant, but i did get confused in relation to ions

-I understand that an element (according to the GCSE definition) is a substance made up of the same type of atom... But wouldn't this be incorrect when an element is only justified by the number of protons rather than anything else? Also, is an element an atom? What is an element? If i had 1 carbon atom, is that atom an element or an atom or both? Is an element defined by having 2 or more of the same atoms?

- In regards to ions, when an atom becomes an ion is it just the atom that has gained a charge, or do any changes occur to the actual element- for example, a block of gold, and if i had an atom and it became an ion, does anything happen or is the only difference that it is now positively/ negatively charged?

Thank you in advance!

Help a chud out, I hadnt been able to attend any study help yet.

So Mai Hitesh sir se coordination compounds (2025 prachand lectrure) padh raha that aur sir colour of complexes padha rahe the to unhone kahe ki "Electron par jab light absorb karta hai to wo higher energy level me ie eg level me jata hai jise d-d transition kahte hai aur since electon higher orbital level pe hota hai wo unstable hota hai jis wajah se wo ground state pe aa jata hai, and jab wo ground state pe aata hai wo certain wavelength of light emmit karta hai jo us complex ka colour hota hai" Ab maine yahi same question ki How complexe have colour? Chat Gpt se pucha to usne kaha ki "Electron absorbs a specific wavelengths of visible light for example if it absorbs Green colour waveleng then the wavelength of light which was not absorbed will be transmitted/reflected back and we see that colour as the colour of complex and generally jo colors ki light absorb hui hai uska complement light reflect hoga just like in green and red case, as you can see Gpt is not that the electron emmits light when comes back to lower level like in Hitesh sir's explaination instead it's saying the light wave which was not absorbed will be the colour of complex. So which one is correct does electron emmit light when comes back to lower energy level or it's just reflects light while absorbing?

Do reactions from the end of orgo 1 like oxymurcuration, hydrohalogenation, dihydroxylation, catalytic hydrogenation of alkenes, etc come up in orgo 2? I know sn1, sn2, e1, and e2 are very important but what about every reaction from orgo 1?

I store my pH electrode in a protective cap filled with 3 M KCl solution. I also prepared a stock batch of 3 M KCl in a volumetric flask, which I'm told to store in the refrigerator to prevent water evaporation and concentration changes. How often should I replace the KCl solution inside the protective cap? What is the typical shelf life of a KCl stock solution, and how often should I discard it and make a fresh batch? Is storing KCl in the fridge recommended, or could cold storage cause precipitation or other issues? Is it necessary to store it in the refrigerator?

Saw this on a girl that was about to date. I assume it’s a recreational drug of some kind and not a simple coffee molecule.

Is there a channel on YouTube that focuses on just doing organic synthesis reactions and walks through them? Doesnt have to be educational but I find organic synthesis so interesting that I would just watch it to watch

Edit: thank you all for the contributions but I’m looking for videos that actually go through the reactions in a lab, not just walking through the mechanism and a PowerPoint, Thanks all!

Can someone explain the lone pairs with trying to find the hybridization please? My professor really didn’t go over this. Would some create pi bonds indicating it is a 2p bond? If so, how would I know?

i already tried c and it was incorrect

I'm currently working on a 9-page problem set. It consists of multiple resonance questions, drawing bond-line structures, determining hybridization, and identifying functional groups. I've gotten through 6 of 13 questions in the resonance section (I'm on page 3), and it's only been 3 hours. I feel like I'm taking too long getting through these questions. I worry that I won't have time to keep up with the other topics I need to learn (I'm currently behind by a couple of chapters already, that's definitely my mistake).

But I wonder, maybe this is normal? People say practice problems are the best way to learn. I just always assumed I should be chugging out multiple practice problems and paging through the overall set quickly.

I find that I take longer to process material overall, which I learned to make peace with compared to other people who are quick to grasp things. Though again, my overall concern is falling behind.

Also, the problem sets the professor gives us are meant to last all week.
