In halosubstituted benzene halogen acts as electron withdrawing group by -I effect.

Q. Which among the following groups shows maximum electron withdrawing effect?

Q. What is the effect of electron withdrawing group on the acidity carboxylic acid?

Q. In Toluene, the methyl group donates electrons to the benzene ring through pi conjugation.

Q. Choose the correct statement regarding the $+R$ or $+M$ effect.

Q. Consider the following four statements
(1) Benzene does not favour the attack of $N{u}^{-}$ 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-
