In which of the following reactions, the product is racemic mixture

Options

A. `CH_3 CHO overset(Dil NaOH)to`
B. `CH_3 COCH_3 overset("dil" NaOH)to `
C. `CH_3 CHO overset( HCN)to`
D.

Answer

A, C, D

Explanation

`CH_3 CHO underset(NaOH) overset(dil)to CH_3 - underset( "*") overset(OH) overset(|)CH -CH_2 - overset(O ) overset(||)C-H `(Racemic micture )
`CH_3 CHO overset(HCN )to CH_3 - overset(OH) overset(|)CH -CN ` ( racemic mixture )
`CH_3 -overset(O ) overset(||)C -CH_3 underset(NaOH) overset(dil) to CH_3 - underset(CH_3) underset(|) overset(OH) overset(|) CH -CH_2 - overset(O) overset(||)C-CH_3` no cheiral so racemic not formed
