Give the correct organic product for the following reaction: 1. NaBH 2. H2O

Answer 1

Concepts and reason

Reduction: Loss of oxygens or addition of hydrogens is called reduction. Draw the major organic product, when aldehyde undergo reduction in presence of sodium borohydride.

Fundamentals

The substance which oxidised in a chemical reaction is called as a reducing agent. The examples for reducing agent are ${\rm{LiAl}}{{\rm{H}}_{\rm{4}}}{\rm{,}}\;{\rm{NaB}}{{\rm{H}}_{\rm{4}}}$ .

${\rm{NaB}}{{\rm{H}}_{\rm{4}}}$ is mild reducing agent. Which reduces aldehydes and ketone to form primary alcohol and secondary alcohol respectively.

The reaction is,

Ans:

Thus, the major organic product is,
