Which of the following compounds would undergo aldol condensation or the Cannizzaro reaction, or neither? Writer the structures of expected products of aldol condensation and Cannizzaro reaction.
i. Methanal ii. 2-Methylpentanal
iii. Benzaldehyde iv. Benzophenone
v. Cyclohexanone vi. 1-Phenylpropanone
vii. Phenylacetaldehye viii. Butan-1-ol
ix. 2,2-Dimethylbutanal

Explanation

(ii ) 2-methylpentanal ( v ) 1- cylohexanone ( vi ) 1-phenylpanone and (vii ) phenylacetaldehyde contain one or more ` alpha ` - hydrogen atoms and therefore , undergo aldol condensation .
(iv) Benzophenone is a ketone having no `alpha`-hydrogen and (viii) butan-1-ol is an alcohol. These neither undergo aldol condensation nor Cannizzaro.s reaction.
