a) (iii) The functional group -C C- represents an alkyne. The first member is ethyne (C_2H_2), the second is propyne (C_3H_4). The third member is butyne (C_4H_6). A possible structure for butyne is but-1-yne: CH_3CH_2C (iv) Compound D (alcohol) can be distinguished from compound B (alkene) using bromine water. • When bromine water (orange-brown) is added to compound B (alkene), it will be decolorized as the bromine adds across the double bond. • When bromine water is added to compound D (alcohol), there will be no observable change (it remains orange-brown). (v) • For the functional group -C-C- (saturated carbon-carbon bond, as in alkanes), the reaction with a bromine molecule is Substitution. • For the functional group -C=C- (carbon-carbon double bond, as in alkenes), the reaction with a bromine molecule is Addition.
