Topic 10 - organic reactions

Question 1

What’s a functional group?

Answer 1

A particular group of atoms which are responsible for how the molecules react (eg. alcohols)

Question 2

What’s an Alkene?

Answer 2

An unsaturated hydrocarbon

Question 3

What’s the general formula for alkenes?

Answer 3

Cn H(2)n

Question 4

What’s a homologous series?

Answer 4

A group of substances with the same general formula (eg. Alkanes or alkenes)

Question 5

What do we seem when we react an alkene with bromine rather than an alkane with bromine?

Answer 5

The alkene made the bromine colourless when mixed, however the alkene didn’t change colour (didn’t react).

Question 6

When alkenes react with steams, what environment is needed to produce alcohols?

Answer 6

High temperatures with an acid catalyst

Question 7

When alkenes burn, do they burn with a smokier flame, or less smokier flame than alkanes?

Answer 7

Smokier flame than alkane, since they have a higher ratio of carbon to hydrogen
