Question 17

A long-chain alkane found in crude oil is hexadecane, $C16H34\text{C}_{16}\text{H}_{34}$ .

Complete the equation for the catalytic cracking of one molecule of $C16H34\text{C}_{16}\text{H}_{34}$ to form two molecules of propene ( $C3H6\text{C}_3\text{H}_6$ ) and one molecule of another hydrocarbon, $Y$ .

\text{C}_{16}\text{H}_{34} \rightarrow 2\text{C}_3\text{H}_6 + \text{...}

[2]

Explain whether hydrocarbon $Y$ is saturated or unsaturated.

An organic impurity found in some crude oil supplies has a relative molecular mass ( $M_r$ ) of $88$ . It contains carbon, hydrogen, and oxygen atoms in a $2 : 4 : 1$ ratio. Determine the molecular formula of this impurity. [Relative atomic masses: $H=1\text{H} = 1$ , $C=12\text{C} = 12$ , $O=16\text{O} = 16$ ]
