Question
The reactivity of compound Z with different halogens under appropriate conditions is given below :
The observed pattern of electrophilic substitution can be explained by
The observed pattern of electrophilic substitution can be explained by
Options
A.The steric effect of the halogen
B.The steric effect of the tert-butyl group
C.The electronic effect of the phenolic group
D.The electronic effect of the tert-butyl group
Solution
(I), (II) and (III) are probable positions as per electronic effect of OH group where electrophile can attack and due to steric hindrance at (II) and (III) positions bulky electrophiles are not preferred like I only preferred at position I, Bromine at positions II and I while chlorine at all three positions.
