Question

Select the incorrect statement among the following:

• A. Benzene undergoes predominantly electrophilic substition reactions
• B. Toluene is more easily sulphonated than benzene
• C. Benzene reacts with $C{Cl}_4$ in the presence of anhydrous $Al{Cl}_3$ to give triphenyl methyl chloride
• D. Benzene reacts with chlorine $\left({Cl}_2\right)$ in presence of light to give benzyl chloride

Answer 1

Answer: (C), (D)

The correct options are
C Benzene reacts with $C{Cl}_4$ in the presence of anhydrous $Al{Cl}_3$ to give triphenyl methyl chloride
D Benzene reacts with chlorine $\left({Cl}_2\right)$ in presence of light to give benzyl chloride

The options C and D are incorrect.
(C) When benzene reacts with carbon tetrachloride in the presence of anhydrous aluminium chloride, triphenyl methyl chloride is not obtained as the product as it is sterically hindered.
(D) Benzene reacts with chlorine in presence of sunlight to form benzene hexachloride $C_6{H}_{6}C{l}_6$ abbreviated as BHC and also called gammaxene.
