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_________.

• 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

Answer 1

The correct option is A the steric effect of the halogen

In the following reaction, the steric of the tetra-butyl group which is attached to the benzene ring. That is why, the reactivity of compound $Z$ with different halogens under appropriate condition and electro-negativity of the halogens is $C{l}_2>B{r}_2>I_2$.
