• # question_answer Two carbon compounds X and Y have the molecular formula ${{\mathbf{C}}_{\mathbf{4}}}{{\mathbf{H}}_{\mathbf{8}}}$ and ${{\mathbf{C}}_{\mathbf{5}}}{{\mathbf{H}}_{\mathbf{12}}}$ respectively. Which one of these is most likely to show addition reaction? Justify your answer. Also give the chemical equation to explain the process of addition reaction in this case.

 $X={{C}_{4}}{{H}_{8}}$ is an alkene. $Y={{C}_{5}}{{H}_{12}}$ is an alkane. X being an alkene i.e., butene is unsaturated compound and will show addition reaction as they have free electrons for bonding. $C{{H}_{3}}C{{H}_{2}}CH=C{{H}_{2}}+{{H}_{2}}\xrightarrow{Pd/Ni}C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}C{{H}_{3}}$ $C{{H}_{3}}CH=CHC{{H}_{3}}+C{{l}_{2}}\xrightarrow{hv}C{{H}_{3}}ClCHClCHC{{H}_{3}}$
