Vedclass · Answer

(D) The reaction of Grignard reagents $(RMgX)$ with aldehydes and ketones follows these rules:$1$. Formaldehyde $(HCHO)$ + $RMgX$ $\rightarrow$ $1^o$ alcohol.$2$. Other aldehydes $(R'CHO)$ + $RMgX$ $\rightarrow$ $2^o$ alcohol.$3$. Ketones $(R'COR'')$ + $RMgX$ $\rightarrow$ $3^o$ alcohol.In option $(a)$,isobutyraldehyde is an aldehyde,so it forms a $2^o$ alcohol.In option $(b)$,acetaldehyde is an aldehyde,so it forms a $2^o$ alcohol.In option $(c)$,methyl isopropyl ketone is a ketone,so it forms a $3^o$ alcohol.Therefore,both $(a)$ and $(b)$ yield a $2^o$ alcohol.

In which of the following reactions is a $2^o$ alcohol obtained as a product?
