Question

Describe the action of alcoholic potassium hydroxide (alc. KOH) on n-propyl bromide

Answer 1

n-Propyl bromide: When n-propyl bromide is heated with alcoholic potassium hydroxide, propene is formed.

\[\ce{\underset{n-Propyl bromide}{CH3 – CH2 – C}H2 - Br + \underset{(alc.)}{KOH} ->[heat] \underset{Propene}{CH3 -} CH = CH2 + KBr + H2O}\]
