Correct statement about photo-chemical smog is:
1 It occurs in humid climate
2 It is a mixture of smoke, fog and $\mathrm{SO}_2$
3 It is reducing smog.
4 It result from reaction of unsaturated hydrocarbon.
Explanation:
: $\mathrm{NO}_2$ and unsaturated hydrocarbons are the primary constituents of photochemical smog. These primary constituents are introduced in the atmosphere via vehicular emissions and industrial processes.

An organic compound having carbon and hydrogen, has $80 \%$ carbon. The empirical formula of the hydrocarbon is
1 $\mathrm{CH}$
2 $\mathrm{CH}_2$
3 $\mathrm{CH}_3$
4 $\mathrm{CH}_4$
Explanation:
: Methane cannot be prepared by Wurtz reaction. Hence, in methane having one carbon atom chain only. In Wurtz reaction is used for the preparation of only those alkanes that contain at least two carbon atoms.
