Solution of a solution of 2 chloro 2 phenyl Methane in the toll in this images slowly in the presence of small amount of sbcl5due to the formation of

Answer 1

Hello dear,

● Answer-

Racemization of (+)-1-chloro-1-phenylethane in toulene occurs as a result of phenyl-ethane *carbocation* formation.

● Explaination-

In presence of toulene, (+)-1-chloro-1-phenylethane reacts with small amount of antimony pentachloride(SbCl5) to form phenyl-ethane carbocation.

C6H5-CH(Cl)CH3 + SbCl5 ---> [C6H5-CH-CH3]+ + [SbCl6]-

Formation of this carbocation leads to racemization of (+)-1-chloro-1-phenylethane in toulene.

Hope this is useful.

Thanks for asking...
