Name the cyclic unsaturated hydrocarbon containing three double bonds.

Select the hydrocarbons which are members of the same homologous series.

${\mathrm{C}}_5{\mathrm{H}}_{10}, {\mathrm{C}}_7{\mathrm{H}}_{12}, {\mathrm{C}}_6{\mathrm{H}}_{10}, {\mathrm{C}}_3{\mathrm{H}}_8, {\mathrm{C}}_4{\mathrm{H}}_{10}, {\mathrm{C}}_7{\mathrm{H}}_{16}$

Out of the given hydrocarbons, which one undergoes substitution reaction?

${\mathrm{C}}_4{\mathrm{H}}_8, {\mathrm{C}}_5{\mathrm{H}}_{12}, {\mathrm{C}}_6{\mathrm{H}}_{10}, {\mathrm{C}}_3{\mathrm{H}}_6$
