The reaction leading to the formation of m-chloro toluene are -
Answers
Answer:
The reaction which gives m-chloro toluene is option C.
Explanation:
(a) Reaction of toluene
The methyl group in toluene is an ortho para directing group.
Toluene on reaction with excess chlorine in the presence of light gives Benzyl chloride.
(b) What will be the product when toluene reacts with chlorine in the presence of AlCl₃?
Toluene on reaction with chlorine and AlCl₃ gives o-chlorotoluene and p-chlorotoluene.
(c)What will be the product of the reaction of nitrobenzene?
In nitrobenzene, the electron density is higher in the meta position and is lower in the ortho and para positions. Due to this, it is meta directing for an electrophilic substitution reaction.
(d) Why reaction of chlorobenzene gives ortho-para products?
In chlorobenzene the resonance effect causes chlorine atoms to release electrons. With the pi-electrons of the ring, the lone pair on the chlorine atom delocalizes. Due to an electrophile assault, the electron release into the ring stabilizes the positive charge at ortho and para locations.
Given attachment specifies the reactions.
Hope it helps!!!
Answer:
(c) will give m-chloro toluene
Explanation:
(A) toluene + excess Cl₂ → benzyl chloride + (Cl₂/AlCl₃) → o-chloro-benzyl chloride + p-chloro-benzyl chloride
(B) toluene + Cl₂/AlCl₃ → o-chlorotoluene + p-chlorotoluene
(C) nitrobenzene + (CH₃Cl/AlCl₃)→ 3-methyl-nitrobenzene + (Sn/HCl) → 3-methyl-aniline + (HNO₂) → 3-methyl-phenol + (CuCl/HCl) → m-chlorotoluene
(D) chlorobenzene + CH₃Cl/AlCl₃ → o-chlorotoluene + p-chlorotoluene.
