(i) An isomer of n-butane

  

 

(ii) 2-propanol

  

(iii)Diethyl ether

 

Solution 2013-2

Reasons:

(i) Alkanes are saturated, i.e. they do not have a carbon-to-carbon double bond, and so do not undergo an addition reaction. Alkenes are said to be unsaturated because of the carbon-to-carbon double bond in their structure, and the double bond in alkenes makes them more reactive than alkanes.

(ii) Ethyne is a highly reactive compound due to the presence of a triple bond between its two carbon atoms.

(iii) Hydrocarbons are used as fuels because they burn in air producing a lot of heat energy.
