Title: SN1/SN2 mechanisms
Post by: Mmm1233 on October 24, 2019, 11:17:11 AM

Why does the P-methoxybezyl chloride follow SN1 reaction mechanism with methanol while P-nitrobezyl bromide follows SN2 reaction mechanism?

Can you draw the cation intermediat for p-methoxybenzyl bromide reaction? Can you draw a similar resonance stabilized cation for the p-nitrobenzyl bromide?

Think about the influence of the substituents on the cation.
