(X g) of ethylamine is subjected to reaction with (NaNO_2 / HCl) followed by water; evolved dinitrogen gas which occupied (2.24 ~L) volume at STP. (X) is ( ) (× 10^ -1 ~g).

Correct answer: 45 Mol.wt.45g CH_3 CH_2 NH_2 NaNO_2+HCl H_2 O CH_3 CH_2-OH+ 14 ~g ~N_2 given : N_2 evolved is 2.24 L i.e. 0.1 mole. i.e. CH_3 CH_2 NH_2 (ethyl amine) will be 4.5 ~g(=0.1 ~mole) Hence the answer =45 × 10^ -1 ~g

(X g) of ethylamine is subjected to reaction with (NaNO_2 / HCl)...

(\mathrm{X} \mathrm{g}) of ethylamine is subjected to reaction with (\mathrm{NaNO}_2 / \mathrm{HCl}) followed by water; evolved dinitrogen gas which occupied (2.24 \mathrm{~L}) volume at STP. (\mathrm{X}) is (\qquad) (\times 10^{-1} \mathrm{~g}).

Correct answer

Step-by-step solution

\underset{\substack{\text{ Mol.wt.45g }}}{\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{NH}_2} \xrightarrow{\mathrm{NaNO}_2+\mathrm{HCl}} \xrightarrow{\mathrm{H}_2 \mathrm{O}} \mathrm{CH}_3 \mathrm{CH}_2-\mathrm{OH}+\underset{14 \mathrm{~g}}{\mathrm{~N}_2}

given :

\mathrm{N}_2

evolved is 2.24 L i.e. 0.1 mole. i.e.

\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{NH}_2

(ethyl amine) will be

4.5 \mathrm{~g}(=0.1 \mathrm{~mole})

Hence the answer

=45 \times 10^{-1} \mathrm{~g}
