The reactivity of compound Z with different halogens under appropriate conditions is given below: The…

1. The steric effect of the halogen
2. The steric effect of the tert-butyl group
3. The electronic effect of the phenolic group
4. The electronic effect of the tert-butyl group

Solution

The reason is the steric hindrance of the tetra-butyl group which is attached to the benzene ring. That is why, the reactivity of compound Z with different halogens under the appropriate condition and electro-negativity of the halogens is ${\mathrm{Cl}}_2 >{\mathrm{Br}}_2>{\mathrm{I}}_2$
