Explanation
Aldol condensation requires an aldehyde or ketone with at least one α-hydrogen atom. Cannizzaro reaction occurs with aldehydes that have no α-hydrogen. Benzophenone has no α-hydrogen and is a ketone, so it undergoes neither reaction. Butan-1-ol is an alcohol, not an aldehyde or ketone, so it undergoes neither reaction.
