Question 1

Alkane

Answer 1

Homologous series of hydrocarbons that contains only carbon- carbon single covalent bonds. They do not have a functional group.

Question 2

Incomplete combustion

Answer 2

Flame produced becomes more smokier and sootier

Question 3

Chemical properties of alkanes

Answer 3

Generally unreactive. Consist of only carbon- carbon single bonds and carbon- hydrogen bonds which are strong and difficult to break.

Question 4

Combustion of alkanes

Answer 4

Burns readily in excess oxygen to produce carbon dioxide and water vapour. It is highly exothermic and makes alkanes good fuel.

Question 5

Substitution reactions of alkanes

Answer 5

Reagent: Cl (g) or Br (g)
Condition: ultraviolet light

Alkane reacts with halogens in the presence of ultraviolet light.

Question 6

Use of alkanes

Answer 6

Fuel for heating
