Bromination of phenyl benzoate
WebThis is an example of a steric effect —an effect caused by the size of the substituent—and we would say that as the size of the alkyl group increases, attack at the ortho position becomes less favourable as a result of steric hindrance. Note that the size of the electrophile can also be a factor in determining the ortho/para ratio: the ... WebAt what position, and on what ring, is bromination of phenyl benzoate expected to occur?
