Write the balanced chemical equation for ethyl chloride treated with alcoholic potassium hydroxide.

A balanced equation is an equation is a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction. When ethyl chloride undergo dehydrohalogenation with alcoholic potassium hydroxide it gives ethylene as main compound as shown below, CH 3 - CH 2 - Cl + KOH → CH 2 = CH 2 + KCl + H 2 O
