Front (Question)

What does a compound name ending in –ane indicate?

Back (Answer)

An alkane - saturated hydrocarbon, single bonds only

Front (Question)

What does a compound name ending in –ene indicate?

Back (Answer)

An alkene - unsaturated hydrocarbon with a double bond

Front (Question)

#10

Front (Question)

unbranched alkenes up to four carbons

Back (Answer)

• Ethene • propene • butene

#11

Front (Question)

Alkanes

Back (Answer)

saturated hydrocarbons whose molecules contain only single covalent bonds

#12

Front (Question)

Chemical properties of alkanes (2)

Back (Answer)

• generally unreactive • burn in combustion reactions Eg. Methane

#13

Front (Question)

complete combustion of a hydrocarbon

Back (Answer)

Burning in excess oxygen to form carbon dioxide and water

#14

Front (Question)

Word equation for complete combustion of methane

Back (Answer)

Methane + oxygen → carbon dioxide + water

#15

Front (Question)

Alkene

Back (Answer)

unsaturated hydrocarbons whose molecules contain one double covalent bond C=C

#16

Front (Question)

Cracking

Back (Answer)

A reaction that breaks large alkane molecules into smaller alkanes and alkenes

#17

Front (Question)

What products are formed in cracking (3)

Back (Answer)

• Smaller alkanes • alkenes • hydrogen

#18

Front (Question)

conditions required for cracking (2)

Back (Answer)

• High temperature • catalyst - e.g. aluminium oxide

#19

Front (Question)

How can you identify saturated vs unsaturated hydrocarbons using bromine water?

Back (Answer)

• Alkene (unsaturated): bromine water which is orange/brown water turns colourless • Alkane (saturated): no change

#20

Front (Question)

ways ethanol can be produced (2)

#21

Front (Question)

ethanol formation from ethene

Back (Answer)

Catalytic addition of steam to ethene at high temperature and pressure

#22

Front (Question)
