Correct Option - 4
Detailed Solution:If the carbonyl compound is sterically crowded, then it will be reluctant to undergo addition reaction. Moreover, attachment of bulkier alkyl group with the carbonyl carbon decreases the partial positive charge resulting into the minimization of attack by R? from RMgBr. So, the order is
