Self Assessment Checklist
| Alkenes | I can do this! | |
| (a) | Describe the alkenes as an homologous series of unsaturated hydrocarbons with the general formula CnH2n. | |
| (b) | Draw the structures of branched and unbranched alkenes, C2 to C4, and name the unbranched alkenes ethene to butane. | |
| (c) | Describe the manufacture of alkenes and hydrogen by cracking hydrocarbons and recognise that cracking is essential to match the demand for fractions containing smaller molecules from the refinery process. | |
| (d) | Describe the difference between saturated and unsaturated hydrocarbons from their molecular structures and by using aqueous bromine. | |
| (e) | Describe the properties of alkenes (exemplified by ethene) in terms of combustion, polymerisation and the addition reactions with bromine, steam and hydrogen. | |
| (f) | State the meaning of polyunsaturated when applied to food products. | |
| (g) | Describe the manufacture of margarine by the addition of hydrogen to unsaturated vegetable oils to form a solid product. | |
