Chemistry - Carbonyl compounds Question with Solution | TestHub

If the carbony carbonyl is stericaly crowded, then it will be reluctant to undergo addition reaction. Moreover, attachment of bulkier alkyl groups with the carbonyl carbon lessens its positive charge resulting into the minimisation of attack by$\stackrel{\cdot \cdot }{\stackrel{-}{\mathrm{R}}}$from RMgBr. So, the order is
