Leah your videos are amazing !! I cannot believe that I am actually starting to enjoy organic chemistry and it is not something I dread doing. Your videos are so easy to understand and so enjoyable. I am doing a pharmacy degree and there is quite a lot of organic chemistry. Thank you very much for making everything so much easier for me. I appreciate it very much!! Looking forward to more.

I just thought of a great way to memorize induction. Atom wants to pull “in” the charge and “duct” tape the “ion” to itself.

at 06:48,is it because of the -COOH bond being attached to an sp2 C(more electronegative than sp3)of the benzene ring that C6-H5-COOH is stronger...due to -I effect??

Hi, at 6:11, wouldnt the benzoic molecule have 2 resonance structures, as the benzene ring has resonance by moving the bonds 1 over? I dont understand why the resonance is the same in both compounds.

@Leah4sci

2 ай бұрын

Yes, benzene does have resonance in the ring itself, but here we only look at resonance that helps stabilize the carboxylate anion to stabilize the conjugate base. Benzene resonating in the ring has no impact on the negative charge. Benzene resonating OUT of the ring towards the carboxylate would only compete with the O- resonating onto the pi bond thus getting in the way. This type of competing resonance REDUCES the anion stabilization as it brings MORE negativity (from the benzene electrons) towards the negative O making it less than ideal

Thank u sooo much leah....may god bless u

So in your Atom video I understood it as for size that the larger the molecule the more stable /happy/unreactive it is, and for Electronegativity the more EN (in the row) want to be negative to make it happy (comparing say C to O, same row different EN). However here I am interpreting it as the more EN in a group is the stronger one. ex @3:45 . They aren't in the same row, but are in the same group so I am trying to figure this out.

These are great thoughts. Keep in mind that this video discusses the inductive effect, in which a halogen is placed downline from an acidic proton. This phenomenon is different than the comparison of the atom that the acidic proton is directly bonded to. (Which I discussed in the video you mentioned.) Since I don't offer tutoring over social media, to get help with questions like this and more, I recommend joining the organic chemistry study hall.

Hi Leah, I'm not sure if I'm understanding this concept correctly but even though chlorine is more electronegative than bromine, bromine is much larger in size affecting stability of the atom. Therefore bromine would be more stable. Doesn't mean that the structure with bromine is more acidic/stronger acid? Thanks

@layanification

8 жыл бұрын

+Theresa Sengpraseuth you are right. Electronegativity matters, but for atoms in the same group, the increase in size increases polarizability which increases stability ( ie Cl vs Br). However, this is only if the atom is attached directly to the acidic hydrogen

I have a question so if we increase the number of carbon then you somewhat increase the strength of electro negativity of carbon like adding up all the individual electronegative value of carbon??

@Leah4sci

2 жыл бұрын

No, that is not the case. Remember that a straight chain of carbons, by itself, would be completely nonpolar. (No difference in electronegativity values from one end to the other.) The inductive effect comes into play when you have a difference in electronegativity between neighboring atoms. For example, adding a halogen on to that chain of carbons.

that trend only applies when a halogen is only bonded to a hydrogen aton.. eg HBr , HI, HCl and HF .. in this case HI is the stronger acid followed by Br ...

What do you mean "you're not going to show that for this kind of molecule" (5:50) ? You didn't explain why.

I meant the resonance form already drawn is the major contributor and pulling out the electron density from the ring does not serve our purposes of ranking the acidity of the two compounds based on the inductive effect.

They will, but they can only move apart so much before other forces kick in (like the rigidity of those sigma bonds that connect them to the carbon).
