question_answer

The product is obtained by the reaction of an aldehyde and hydroxylamine is :

A) hydrazone         

B) aldoxime

C) primary amine  

D) alcohol

Correct Answer: B

Solution :

Aldehydes with hydroxyl amine \[(\overset{\centerdot \,\centerdot }{\mathop{N}}\,{{H}_{2}}OH)\] form aldoxime and ketones with\[N{{H}_{2}}OH\] gives ketoxime. Aldehydes upon reaction with Grignard reagent followed by acidic hydrolysis yield alcohol Aldehydes and ketones with hydrazine \[(N{{H}_{2}}N{{H}_{2}})\] forms hydrazone
