When answering this question, you should take structural isomerism and stereoisomerism into account. A colourless liquid, $\text{C}_5\text{H}_{11}\text{Cl}$, is present as a mixture of two optical isomers. On heating with sodium hydroxide in ethanol, only a mixture of two alkenes is produced. What might the colourless liquid be?
- A$(\text{CH}_3\text{CH}_2)_2\text{CHCl}$
- B$\text{CH}_3\text{CH}_2\text{CH}_2\text{CHClCH}_3$
- C$\text{CH}_3\text{CH}_2\text{CCl(CH}_3)_2$
- D$(\text{CH}_3)_2\text{CHCHClCH}_3$
