### Solution 2011-4

### Solution 2013-1

(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.

### Solution 2013-3

Equations:

(i) CH_{3}I + 2[H] → CH_{4} + HI

Iodo Methane

(ii) CH_{3}CH_{2}OH + H_{2}SO_{4}→ CH_{3}CH_{2}HSO_{4}
+ H_{2}O

CH_{3}CH_{2}HSO_{4}→ CH_{2}=CH_{2}
+ H_{2}SO_{4}

(iii)CaC_{2}
+ 2H_{2}O → Ca(OH)_{2}
+ C_{2}H_{2}↑

(iv) C_{2}H_{5}Br + NaOH → C_{2}H_{5}OH
