Q. Which alkyl halide exhibits complete racemisation in reaction?

 2700  240 Haloalkanes and Haloarenes Report Error

Solution:

All the molecules undergoing reaction shows racemisation as there is formation of 2 types of product in equal amount. Out of all these 4 alkyl halides, i.e benzylic chloride has the strongest tendency to undergo here thus leading to formation of racemic mixture as it contains benzylic carbocation which is most stable.
