Schemat punktowania
(i) [1] for electrophilic addition. Do not accept nucleophilic addition or addition alone. (ii) [1] for the structural formula showing both chlorine atoms on the carbon atoms of the former double bond; do not accept the molecular formula C6H12Cl2. (iii) [1] for three repeating units of two carbon atoms each, joined through the carbon atoms of the former double bond, with an ethyl group on every carbon of the chain and continuation bonds shown. Ignore brackets and n.
