Question

Select the letter A to H for the correct answer corresponding to the statement.

A. Ammonical $\mathbf{CuCl}$ B. Trichloromethane

C. Trichloroethane D. Bromine solution

E. Aqueous $\mathbf{KOH}$ F. Ethene

G. Soda-lime H. Ethyne

The substance which reacts with Bromoethane to give Ethanol.

Answer 1

1. The reaction of a haloalkane with aqueous Potassium hydroxide ($\mathbf{KOH}$) gives a substitution product.

2. So, when Bromoethane reacts with aqueous Potassium hydroxide, Ethanol is obtained along with Potassium bromide.

3. The chemical equation is

$$\begin{gathered} {\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{Br}\left(l\right)+\mathrm{KOH}\mathit{\left(}aq\mathit{\right)}\mathit{}\mathit{\to }\mathit{}{\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{OH}\left(l\right)+\mathrm{KBr}\left(s\right) \\ \mathrm{Bromoethane}P\mathrm{otassium}\mathrm{Ethanol}\mathrm{Potassium} \\ \mathrm{hydroxide}\mathrm{bromide} \end{gathered}$$

4. Therefore, aqueous Potassium hydroxide reacts with Bromoethane to give Ethanol.

5. Hence, the correct answer corresponding to the statement is E.
