wait a minute... for the inductive example, isn't the molecule with the halogen further away from the OH going to be the stronger acid because the other molecule will have intramolecular hydrogen bonding??

@drsands71 Both can have H-bonding so the difference to focus on is the Br location.

Man... I dont get something.... oxygen is more electronegative than bromine.... so.... the minus charge is supposed to go to the oxygen..... :S

[EnderlePhD]

@JohnReyes32 You are thinking the right way. However, the idea that the most electronegative atom will receive the negative formal charge doesn't always happen. That concept is trumped by the octet rule and minimizing formal charge.

you are such an amazing teacher! Thank you posting this!!!

this is good. thanks. but i wish you'd done more about inductive effect

hahaha.. the anti-woo..
