Thank you so much Mr. Mennella for making these videos. @16:35 why could the carboxylate make hydrogen bonds with the -OH? Based on resonance theory, isn’t the electron density too disperse to form H bonds in carboxylate? Thank you in advance!

No, it is not. I know this is an old comment that was directed at him, but he probably did not see it and I am just seeing it now. Hydrogen bonds can occur even between Oxygen gas (O2) and a hydrogen atom attached to an electron withdrawing group (like N or O). Nitrogen is less electronegative than oxygen and needs to be partially negative to do hydrogen bonds with hydrogen only if that hydrogen in which is H-bonding with is attached to another N. For example, H-bonding would not be possible between N2 and NH3 for this reason (N2 is not partially negative). These rules are rather arbitrary, and what is considered H-bonding is probably not as definitive as one may think.
