Metallic Crystals 24-25 understand that a metal can be described as a giant structure 1.46 of positive ions surrounded by a sea of delocalised electrons 24-25 explain the electrical conductivity and malleability of a metal 1.47 in terms of its structure and bonding. Organic Chemistry 149-154 explain the terms homologous series, hydrocarbon, saturated, 3.1 unsaturated, general formula and isomerism Alkanes 3.2 156 recall that alkanes have the general formula CnH2n+2 150 draw displayed formulae for alkanes with up to five carbon 3.3 atoms in a molecule, and name the straight-chain isomers 157, 165 recall the products of the complete and incomplete 3.4 combustion of alkanes 157 describe the substitution reaction of methane with bromine to 3.5 form bromomethane in the presence of UV light. Alkenes 3.6 158 recall that alkenes have the general formula CnH2n 152 draw displayed formulae for alkenes with up to four carbon 3.7 atoms in a molecule, and name the straight-chain isomers (knowledge of cis- and transisomers is not required) 158 describe the addition reaction of alkenes with bromine, 3.8 including the decolourising of bromine water as a test for alkenes. Ethanol 159-160 describe the manufacture of ethanol by passing ethene and steam 3.9 over a phosphoric acid catalyst at a temperature of about 300°C and a pressure of about 60–70 atm
