Does Benzophenone Undergo Cannizzaro?

Compound (iv) Benzophenone is a ketone having no α-hydrogen atom and compound (viii) Butan-1-ol is an alcohol. Hence, these compounds do not undergo either aldol condensation or cannizzaro reactions.

Which is the undergo Cannizzaro reaction?

When a mixture of formaldehyde and a non-enolizable aldehyde reacts with a strong base, the latter is reduced to alcohol while formaldehyde is oxidized to formic acid. This is known as the cross Cannizzaro reaction.

Which will not show Cannizzaro?

α− hydrogen means a hydrogen which is bonded with an α− carbon and α− carbon is the first carbon attached to the functional group. Here we see that only Acetaldehyde contains an α− hydrogen so it will not undergo the Cannizzaro reaction.
