Which one of the following will give racemised product in C2H5OH? (a) (b) (c) (d)

The chiral center is present in (c) only. For the reactant to give a racemic mixture the compound must have at least one chiral carbon atom. The reaction of formation of a racemic mixture of option (c) is given below: 37. Which of the following reactions follows SN2 mechanism (a) - - 3 3 CH Br + OH CH OH + Br -> (b) Θ Θ 3 3 3 3 CH CH(Br) - CH + OH CH CH(OH) - CH + Br -> (c) 2 -H O 3 2 2 2 C H C H O H C H =C H -> (d) The order for the 2 N S reaction is 1 2 3 . The first option represents the best conditions to proceed by N S 2 mechanism because there will be the formation of a pri
