-Formation of polymers
-A chemical feedstock

22
Q

What are alcohols used for?

A

Beverages
Perfumes
Aftershave
Mouthwash
Solvents

23
Q

What are carboxylic acids used for?

A

Ethanoic acid is used in vinegar

24
Q

Combustion reaction of alcohols

A

Combust easily, burn with a blue flame

Produce carbon dioxide and water

25
Q

Combustion reaction of carboxylic acids

A

They can undergo combustion but they are not widely used as fuel

26
Q

Combustion reaction of alkenes

A

Complete will produce carbon dioxide and water

Incomplete will result in a smoky yellow flame

Both types of alkene combustion release less energy per mole than alkanes
