Vedclass · Answer

(C) The reduction of aldehydes and ketones using $NaBH_4$ or $LiAlH_4$ yields primary or secondary alcohols. $1.$ Aldehydes $(RCHO)$ are reduced to primary alcohols $(RCH_2OH)$. $2.$ Ketones $(RCOR')$ are reduced to secondary alcohols $(RCH(OH)R')$. $3.$ Tertiary alcohols cannot be obtained by the reduction of aldehydes or ketones because they require a carbon atom bonded to three other carbon atoms,which is not possible through simple reduction of the carbonyl group. $4.$ $2$-Methylpropan-$2$-ol is a tertiary alcohol,hence it cannot be obtained by this method.

Which of the following cannot be obtained by the reduction of an aldehyde or a ketone using $NaBH_4$ or $LiAlH_4$?
