Question

Write the structure of the product of the following reaction:

\[\begin{array}{cc}
\ce{CH3 - CH2 - CH - CHO ->[NaBH4]}\\
|\phantom{....}\\
\ce{CH3}\phantom{.}
\end{array}\]

Answer 1

The −CHO group is reduced to −CH₂OH.

\[\begin{array}{cc}
\ce{CH3 - CH2 - CH - CHO ->[NaBH4] CH3 - CH2 - CH - CH2OH}\\
\phantom{...}|\phantom{................................}|\phantom{.}\\
\phantom{......}\ce{\underset{2-Methylbutanal}{CH3}}\phantom{....................}\ce{\underset{2-Methylbutan-1-ol}{CH3}}\phantom{}
\end{array}\]
