Question

A student reacted acetophenone, shown below, with sodium borohydride (NaBH4) in methanol to afford products A

and B. The student then treated these products with sodium hydride (NaH) and an alkyl bromide to form products X

and Y.


Would it be possible for the student to physically separate the mixture of products A and B? What about X and Y?

Provide a one-sentence explanation for your answers.

Explanation / Answer

the products A and B are optical isomers optical isomers are differ in the solubiltiy so that we have to crystallise those isomers by adding the proper opticalactive strong base compound so that it will give two different compounds with respect to R and S alcohol compounds based on solubility we can seperate and after that add suitable acid to it to get back seperated products
