Q

What is an addition reaction?

A

Alkene reacting with halogens (eg hydrogen or bromine)

20
Q

What happens to the boiling point of a carboxylic acid as the number of carbons increases? + why?

A

Boiling point gets higher because the Van der Waal forces are stronger the higher the number of carbons

21
Q

Why are larger carboxylic acids less soluble than smaller ones?

A

Long hydrocarbon part of molecule makes it more difficult for them to dissolve

22
Q

What is a homologous series?
