leah4sci.com/organicchemistry/ Presents Electron Arrow Pushing for Resonance and Mechanisms
Organic chemistry is all about UNDERSTANDING how reactions happen, and electron pushing arrows SHOWS how electrons react, and what happens as a result. If you understand this concept, you are well on your way to understanding Organic Mechanisms.
Many students struggle with organic chemistry because they try to memorize rather than understand the concepts and mechanisms. My goal is to break down the concepts so that you can understand and apply them to your homework, quizzes and exams
If you enjoyed this video please show your appreciation by giving it a thumbs up; and subscribe to my channel for quick access to all new tutorial uploads
I will be creating quizzes to help you study the concepts in this quiz. These will be available on my website shortly

You are the woman! Thank you so much for these videos! My professor talks really fast due to the fact that we had many snow closings and everyone disrupts her with off topic chats. So it was hard to hear her. But you broke it down even further. Thank you so much! I didn't get resonance until now that I see it. The electrons on the most negative atom will move to the closest positive carbon.

Jan 6, 2014. towards the end of ochem I we began discussing mechanism and I sort of didn't do too hot but managed to get a B for the class. After watching your video, I'm kicking myself because its basically following and accounting for electrons. Your idea to do brief FC checks to stay on course is great.

@emmanuelletoussaint287 2 года назад

Hi! Currently taking organic chemistry. For the second example of cyclopentane, could you add the double bond in the structure instead of a lone pair?

@Leah4sci 2 года назад

No, we wouldn't be able to do that because the next door carbon would be exceeding the octet rule with five pairs of bonding electrons - 1 single bond and 1 double bond to carbons, as well as 2 single bonds to hydrogens.

regarding the mechanism arrows continued 12:54, why didn't you add the halogen to the positively charged carbon..? I thought that the positive charge carbon will be attracted to the negative halogen.? please explain ):

@Leah4sci 3 года назад

Yes, you are right. That is the correct continuation of the hydrohalogenation reaction mechanism. But as I say at 13:05: “I will discuss the mechanism of this reaction in greater detail in an upcoming video.” You can find that video by visiting leah4sci.com/hydrohalogenation Thanks for commenting!

@916213 4 года назад

@serene9532 6 лет назад

11:10 why are pi-bonds "more negative"? 🤔

@serene9532 6 лет назад

You say it is because "They go above and below the molecule". But how does that make them more negative?

@Leah4sci 6 месяцев назад

Think of it this way: The electrons in a regular bond are stuck between 2 atoms and less likely to be distracted by what's around them. But electrons in a pi bond are hovering above and below and more easily influenced by their environment thus more likely to attack positives within reach
