Which of the following will undergo aldol condensation ?

Options

A. `CH_(3)-CHO`
B.
C. `CH_(3)-overset(O)overset(||)C-CH_(3)`
D. `CH_(3)-overset(CH_(3))overset(|)underset(CH_(3))underset(|)C-CHO`

Answer

B, D

Explanation

Necessary condition for aldol condensation is the presence of atleast one `alpha` H-atm. Hence, `C_(6)H_(5)CHO" and "(CH_(3))_(3)C"C"HO` do not undergo aldol condenstation as the both do not have any `alpha`-hydrogen atom.
