ChemistryFunctional groups: Alkanes, alcohols, carboxylic acids and estersGCSEOCR Created by: Nicole StevensCreated on: 17-04-13 17:14 What are alkanes made up of? chains of carbon atoms surrounded by hydrogen atoms. 1 of 8 What bonds do alkanes contain? single covalent bonds between carbon atoms meaning they are saturated compounds. 2 of 8 What is the formula for alkanes? Cn+H2n=2 3 of 8 Why don't alkanes react? Because the C-C and C-H bonds in them are difficult to break. 4 of 8 What bonds do alkenes contain? They contain some double bonds between carbon atoms meaning they are unsaturated compounds. 5 of 8 what makes alkenes react? The presence of double bonds mean that alkenes can react in a way that alkanes can't 6 of 8 What is the formula for alkenes? Cn+H2n 7 of 8 how do you test to distinguish between an alkene and alkane? By using bromine water, it is usually brown/orange but it becomes colourless when shaken with an alkene. 8 of 8
