Question 22

Conventional liquid fuels derived from crude oil consist of a mixture of hydrocarbons. Modern alternative fuels and additives often contain other elements, and crude oil fractions must be desulfurised to remove harmful sulfur-containing impurities.

Which of the following chemical formulae represents a hydrocarbon?

A

CH3(CH2)4COOCH3\text{CH}_3(\text{CH}_2)_4\text{COOCH}_3CH3​(CH2​)4​COOCH3​

B

CH3CH2CH(CH3)CH2CH3\text{CH}_3\text{CH}_2\text{CH}(\text{CH}_3)\text{CH}_2\text{CH}_3CH3​CH2​CH(CH3​)CH2​CH3​

C

CH3CH2CH2SH\text{CH}_3\text{CH}_2\text{CH}_2\text{SH}CH3​CH2​CH2​SH

D

CH3CH2CH2OH\text{CH}_3\text{CH}_2\text{CH}_2\text{OH}CH3​CH2​CH2​OH
