X = number of groups that show -I effect when attached directly to benzene :

(1) structure

(2) structure

(3) structure

(4) structure

(5) structure

(6) structure

(7) structure

(8) structure

(9) structure

(10) structure

Find the value of X.

Answer:

Solution:

-I groups : SO₃H, C≡N, C≡CH, COOH, NO₂, CF₃ and OH. That is 7.

CH₃ is +I. Phenyl and cyclopropyl carbons have nearly the same electronegativity as the ring carbon, so they are not counted. X = 7.
