Vedclass · Answer

(C) Aldol condensation occurs in aldehydes or ketones that possess at least one $\alpha$-hydrogen atom.$CH_3CHO$ has $3 \ \alpha$-hydrogens.$CH_3CH_2CHO$ has $2 \ \alpha$-hydrogens.$C_6H_5CH_2CHO$ has $2 \ \alpha$-hydrogens.$(CH_3)_3CCHO$ (pivalaldehyde) has no $\alpha$-hydrogen atom because the $\alpha$-carbon is bonded to three methyl groups and the aldehyde group,leaving no valency for hydrogen.Therefore,$(CH_3)_3CCHO$ will not undergo aldol condensation.
