Question

What happens when:

(Give chemical equations only)
(i) Methane reacts with nitric acid at ${400}^{o}C$?
(ii) Ethylene reacts with $HI$?
(iii) Ethyl alcohol is heated with conc. $H_2{SO}_4$ at ${140}^{o}C$

Answer 1

(i) ${CH}_4+H{NO}_3\underset{}{\overset{{400}^{o}C}{\to }}\underset{\text{Nitromethane}}{{CH}_3{NO}_2}+H_{2}O$
(ii) ${CH}_2={CH}_2+HI⟶{CH}_3{CH}_{2}I$
(iii) $C_2{H}_{5}OH+H_2{SO}_4⟶\underset{\text{Ethyl Hydrogen Sulphate}}{C_2{H}_{5}H{SO}_4}+H_{2}O$
$C_2{H}_{5}H{SO}_4+C_2{H}_{5}OH\underset{}{\overset{{140}^{o}C}{\to }}\underset{\text{diethyl ether}}{C_2{H}_5-O-C_2{H}_5}+H_{2}S{O}_4$
