Question

Primary nitroalkanes are obtained in good yield by oxidising aldoximes with the help of ______.

Options

• trifluoroperoxy acetic acid

• acidified potassium permanganate 

• concentrated nitric acid

• potassium di chromate and dilute sulphuric acid

Answer 1

Primary nitroalkanes are obtained in good yield by oxidising aldoximes with the help of trifluoroperoxy acetic acid.

Explanation:

\[\begin{array}{cc}

\ce{R\underset{Aldoxime}{CH = N}OH ->[(O)][CF3COOOH] RCH = N^+ - OH <=> \underset{(1^\circ nitroalkane)}{RCH2NO2}}
\end{array}\]
