Write the chemical equation for the following.
Ethyl chloride treated with alcoholic potassium hydroxide.
Answer
Answer
AIEquation: $\mathrm{C_{2}H_{5}Cl} + \mathrm{KOH} \xrightarrow{\text{alcoholic}\text{ }\text{KOH}\text{,}\text{ }\text{heat}} \mathrm{C_{2}H_{4}} + \mathrm{KCl} + \mathrm{H_{2}O}$
Product: ethene
Ethyl chloride undergoes dehydrohalogenation (elimination) to give ethene.
