*Multiple options can be correct
QUESTION: 6

The reactivity of compound Z with different halogens under appropriate conditions is given below: (JEE Adv. 2014)

The observed pattern of electrophilic substitution can be explained by

Solution:

—OH group is strongly activating and o, p-directing due to +M effect. Thus positions a, b and c are the sites for attack by an electrophile. However, sites b and c are not preferred by bulky electrophile due to steric crowding. Thus more bulky electrophile (like I2) can attack only site a, which is least sterically hindered, a bit smaller electrophile (Br2) can attack at sites a and also b (relatively less sterically hindered site) and the smallest electrophile (Cl2) can attack all the three sites, viz., a, b and c (most sterically hindered site).

*Multiple options can be correct

Solution:
