Exercise 1

${\mathrm{RCONH}}_2$ on reduction with lithium aluminium hydride gives:

Fusion of $\mathrm{Na}$ with aniline gives mainly:

Aniline is prepared in the presence of $\mathrm{Fe}/\mathrm{HCl}$ from:

Name the catalyst used to bring down the reaction:

Indicate which nitrogen compound amongst the following would undergo Hofmann reaction $($i.e., reaction with ${\mathrm{Br}}_2$ and strong $\mathrm{KOH})$ to furnish the primary amine $\left(\mathrm{R}-{\mathrm{NH}}_2\right)$:

When aniline reacts with oil of bitter almonds $\left({\mathrm{C}}_6{\mathrm{H}}_5\mathrm{CHO}\right)$, condensation takes place and benzal derivative is formed. This is known as:

The product $\mathrm{P}$ for the above given reaction will be:

${\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{NH}}_2 \underset{0°\mathrm{C}}{\overset{{\mathrm{NaNO}}_2/\mathrm{HCl}}{\to }}\mathrm{X}\stackrel{\mathrm{CuCN}}{⟶}\mathrm{Y}\stackrel{{\mathrm{H}}_2\mathrm{O}/{\mathrm{H}}^{+}}{⟶}\mathrm{Z},$ $\mathrm{Z}$ is identified as:
