Which of the following reaction is correct?
$\mathrm{C}_2 \mathrm{H}_5 \mathrm{CONH}_2+\mathrm{Br}_2+\mathrm{NaOH} \rightarrow \mathrm{C}_2 \mathrm{H}_5 \mathrm{CH}_2 \mathrm{NH}_2+\mathrm{Na}_2 \mathrm{CO}_3+\mathrm{NaBr}+\mathrm{H}_2 \mathrm{O}$
$\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{NH}_2 \xrightarrow[\mathrm{H}_2 \mathrm{O}]{\mathrm{HNO}_2, 0^{\circ} \mathrm{C}} \mathrm{CH}_3 \mathrm{CH}_2 \mathrm{OH}+\mathrm{N}_2+\mathrm{HCl}$
