The structures of five organic compounds, C, D, E, F and G are shown.
Answer the following questions about these compounds.
(Each compound may be used once, more than once or not at all.)
State which compound, C, D, E, F or G:
(a) on halogenation will form F.
(b) is an alcohol.
(c) is an isomer of 2-methyl propane.
(d) is in the same homologous series as ethene.

(a) G — ethene (G) on halogenation, i.e., addition of bromine, forms 1,2-dibromoethane (F).
(b) D — it contains the –OH (hydroxyl) functional group, so it is an alcohol.
(c) E — 2-methyl propane has the formula C4H10. Compound E (n-butane) is a saturated hydrocarbon with the same molecular formula C4H10, so it is an isomer of 2-methyl propane.
(d) C — ethene belongs to the alkene series (contains a C=C double bond). Compound C also contains a carbon-carbon double bond, so it belongs to the same homologous series as ethene.
