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.

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 жыл бұрын

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.

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

@serene9532

6 жыл бұрын

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

@Leah4sci

5 ай бұрын

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
