Question
Consider the following four statements
(1) Benzene does not favour the attack of Nu− on itself.
(2) On benzene ring E+ can attacks easily because benzene ring is electron rich
(3) Benzene ring does not undergo addition reaction readily because after addition reaction benzene ring loses its aromatically.
(4) When electron withdrawing groups are present on benzene ring, attack of Nu− on benzene nucleolus becomes easy.
Out of these statements, correct statements are-

Solution
The correct option is D 1, 3 and 4
1. Benzene have high electron density so Nu− attack not possible. It is only possible in the case when a strong withdrawing group is present.2. Benzene does not undergo addition reaction as after addition Benzene ring loses aromaticity & only through EAS, E+can attack on Benzene.Correct Option - A(1,3,4).
