Organic Chemistry

2. the measurement of the flow properties of a material. It’s ‘thickness’
3. the breaking down of long chain alkanes into more useful short chain alkanes and alkenes using a catalyst (aluminium oxide) and heat.
5. a family of compounds with the same general formula and similar chemical properties.
7. a mixture of hydrocarbons
11. a process used to separate the components of a liquid mixture that have different boiling points using a fractioning column and distillation.
15. a family of saturated hydrocarbons with the general formula CnH2n+2

1. a bond formed by the sharing of one or more pairs of electrons between 2 atoms.
4. with a plentiful supply of oxygen a fuel will burn completely to produce carbon dioxide and water.
5. a substance containing only carbon and hydrogen atoms
6. a family of unsaturated hydrocarbons with the general formula CnH2n
8. molecules containing one or more double bonds
9. molecules containing only single bonds
10. the tendency of a substance to vapourise
12. the chemical reaction of a fuel with oxygen, producing energy (heat) ‘burning’.
13. combustion if limited supply of oxygen is available a fuel will undergo incomplete combustion producing poisonous carbon monoxide gas.
14. compounds with the same molecular formula but different structural arrangement of the atoms
