When Friedei-Carfts alkylastion of benzene is carried out with 1 equivalent of tert -butyl chloride, a long amount of para-di-tert-butyl benzene is formed along with monosubstitution product.
Why does not all the bezene react to give tert - butyl benzene
(the momo- substitution product )?
A. The tert- bustly substituent activate the benzene ring to further substitution
B. The reaction is bimlecular, so two tert-bustly choride molecule combine with one bezene molecular
C. The tert-butyl substituent is large and favours reaction at para -position .
D. The disbstituted product is favoured in favoured in eqilibrium with mono-substitutedc ring.
