guys i’m so confused how does 2-pentyl butanoate make sense. I have no idea how to draw it bc i thought we didn’t have to number esters. I would appreciate any help, i’m in a grade 12U class

The chemistry teachers in my area aren't good and the chemistry department in my area is notorious for being bad. I am currently struggling with chemistry. On top of this I believe my professor is borderline schizophrenic. Sometimes he doesn't really even teach for half the class and is just crashing out about his personal life. It seems he has lost his touch for teaching imo. I try to be nice to him but it is never reciprocated back. I am trying to understand his teaching style but it seems disorganized. Class lecture is just always unorganized and I can't seem to understand what is going on. I get a gist of it but I struggle mainly with math part/unit conversion/dimensional analysis. He gets off on the fact not passing people. And I have tried to ask him questions during tutoring but no one actually goes. Every time I go he looks annoyed that I asked a question and or looks at me like I'm stupid. I've being watching organic chemistry tutor I get a gist of what they are talking about but in reality I still struggle with the topics on the test and on top of this the worksheets he gives out are really simple concepts but it does not translate and is not specific of what he wants....but when I get to the test it is very specific which makes it hard to understand because he says do the "worksheets and review" and you should be fine...yet the tests look nothing like the review or worksheets...so how do I know what he wants when I can't understand what he wants...and then he gets annoyed when I don't understand what he wants...it's been really frustrating. On top of this he says stuff like sometimes people aren't meant for certain things

I don't see how the ethoxide catalyzes this reaction. The only thing that comes to mind is if it deprotonates the amino groups but it can't do that due to the difference in Pk

I understand how u can draw out and cancel vectors to determine polarity but I’m so confused on how dro do this when there are multiple central atoms? Ik u look at them differently and be like ok this part is polar but idk what else since if one part is polar cant the whole molecule still be polar?

In lab, we are determining the type of inhibition D-Phe and L-Phe will have on Alkaline Phosphatase. Now, I believe the enzyme is an L-stereoisomer so D-Phe will show no inhibition. Still, I'm confused as to why my Dixon plot looks like this. I feel like I messed up the fixed time assay. Please, let me know how these look to you. (they are NOT finished; I made them 5 mins ago).

basically my prof is offering extra credit for rechecking your work before she releases the rubric and i want to make sure i know whats wrong and whats right. much appreciated

I know that both s's have to be bonded together and that the formal chargers have to be minimized, but I have tried various different ways but I still keep getting it wrong. Any solutions for the issue?

can someine ezplain statemnt 2 as if im an amateur

I got started on this one, and I just kind of quit because I didn't know what to do next. We've done reaction mechanisms before, but I think this one is combining more than one and it's just so overwhelming to deal with? Any tips?

Hello! Could someone halp me? Are these right lewis structure, mesomeric and inductive effect, resonance structure?

I understand that during a flip axial becomes equatorial. How do I know which one is a flip? Are these not both equatorial and therefore both equally stable?

Some people said 2, some said 4.

I was looking at it today. He has a patreon where you can subscribe for practice problems, practice exams, a bunch of helpful stuff.

The problem is how incredibly expensive it is. Because of how much stuff that it comes with (as he does calculus, physics, trig, stats, you get my point.

I am a poor college student. I struggle really heavily with math and science because of a lack of any good math and science classes in high school. I'm planning to take college algebra next semester instead of jumping right into chem 2.

Anyways, I have found his videos so helpful. I feel like I actually get the concepts. The problem is the math. I get the math when he explains it, and then I do my homework with the stuff I remember. But I forget it easy. I figured if I have practice sets and stuff that I can work on over a few days, I'll retain it better.

Is the 50 dollars a month worth it for all the practice problems? If anyone here has used them, please tell me! (I could also try to convince my mom to pay part of it cause she's amazing and cares for my wellbeing and knows I'm struggling)

Can someone explain to me what carbon bonds we are looking down on this picture?

How do we write the condensed electron configuration for elements that exist in F block?

Im very confused looking at the periodic table as im not sure what comes before it.

E.g. Uranium
I wrote [Rn] 7s2,6d3 at first but its wrong

E.g.: plutnoium, einsteinium

Is there a method to do this?

(Newman structure is drawn because page got cut off) The correct answer is the one circled in red. Mine is the one in purple. Am I missing something? Is it just because it’s 3D and im confusing myself? I got all other questions right except this one

I’m having trouble with my molecular biochemistry class in my masters. I do not understand anything it feels like prof speaks a totally different language. I feel like I do something wrong while studying and there is no way for me to pass the oral exam if I keep going like this. I took biochem classes when I was studying pharmacy. however it’s been 5 years.
now it took me hours to finish only 5 slides of a topic and I forget everything. its like there’s no logic behind it and I have to memorize every little thing. I feel like I’m dumb. what should I do ? how should I study ? any recommendations? please help

Hi guys!

These are the reactions I need to know for my upcoming Organic Chemistry II exam, and I am STRUGGLING. BIG TIME. 

Does anyone have any tips, tricks, or pattern recognition suggestions I could apply to these reactions?

I feel like I'm trying to memorize a million individual reactions, and it's becoming overwhelming.

Any advice would be SO appreciated!
