The question was posed to me at a job interview.

I would like to ask this question from Halogenation topic in portion Halogenation of Unit Processes

Answer 1

The correct answer is (b) Alkene

For explanation I would say: For example, when propylene dichloride is treated with an alcoholic solution of potassium hydroxide at ordinary temperatures, a-chloropropylene will be formed. Therefore in presence of Alcoholic KOH we convert Alkyl to Alkene (double bond).
