Cannizzaro reaction is not given by:a)Formaldehydeb)Acetaldehydec)Benz...
Cannizzaro reaction is not given by acetaldehyde.
Explanation:
Cannizzaro reaction is a disproportionation reaction of aldehydes in which one molecule of aldehyde is reduced to alcohol and another molecule is oxidized to carboxylic acid. This reaction is mainly observed in aldehydes which do not have a hydrogen atom attached to the carbonyl carbon. The reaction involves the transfer of a hydride ion from one molecule of aldehyde to another molecule.
The given options are:
a) Formaldehyde
b) Acetaldehyde
c) Benzaldehyde
d) Trimethylacetaldehyde
Out of these options, acetaldehyde is the only aldehyde which has a hydrogen atom attached to the carbonyl carbon. Hence, it cannot undergo Cannizzaro reaction as there is no hydride ion available for transfer.
On the other hand, formaldehyde, benzaldehyde, and trimethylacetaldehyde do not have a hydrogen atom attached to the carbonyl carbon and can undergo Cannizzaro reaction.
Therefore, the correct answer is option B, acetaldehyde.
