Question

The gas evolved when methylamine reacts with nitrous acid is:

विकल्प

• \[\ce{NH3}\]

• \[\ce{N2}\]

• \[\ce{H2}\]

• \[\ce{C2H6}\]

Answer 1

\[\ce{N2}\]

Explanation:

Chemical reaction takes place during reaction of methylamine with nitrous acid is as follows:

\[\begin{array}{cc}
\ce{CH3\underset{Methylamine}{-NH2} ->[HNO2] CH3 - \overset{+}{N} ≡ NCl-}\\
\phantom{.........................}\ce{↓^{ΔH_2O}}\\
\phantom{...................}\ce{\underset{Methanol}{CH3OH} + N2↑}
\end{array}\]
