29
Q

What is an isomer?

A

Molecules with the same molecular formula but a different structure

30
Q

Explain the term alkene

A

Hydrocarbons with double carbon bonds (C=C)

31
Q

Which is more reactive alkanes or alkenes, why is this?

A

Alkenes, this is caused by the double carbon bond

32
Q

What allows molecules to be added on?

A

C=C

33
Q

Alkanes are said to saturated, why?

A

Because of the single bond between carbons

34
Q

Alkenes are said to be unsaturated, why?

A

Because of the double carbon bonds

35
Q

How can you test for saturation?

A

Add bromine water to an alkane/alkene and shake, if an alkene (unsaturated) it will turn colourless and if an alkane (saturated) it will stay colourful

36
Q

What does hydrogenation mean?

A

Adding hydrogens

37
Q

What does halogenation mean?

A

Adding halogens

38
Q

What does hydration mean?

A

Adding water

39
Q

“Supply does not always meet demand” True or false?

A

True

40
Q

What does “cracking” mean?
