The treatment of alkyl halide with aqueous KOH solution leads to the formation of alcohols because -
Aqueous KOH ionises to form hydroxyl ions ( OH- ) . Since OH- ion is a strong nucleophile it brings about substitution reaction with alkyl halides forming alcohols.
KOH (aq) --------------> K+ (aq) + OH- (aq)
RCl + OH - (aq) ------------> R-OH + Cl- (aq)
but with alcoholic KOH solution ,an alkene is formed .
This is due to formation of an alkoxide ion (RO- ) . The alkoxide ions are much stronger bases than OH- ions and eliminates a molecule of HCl from alkyl halide to form alkenes
C2 H5 Cl + KOH (alcoholic) ------------> CH2 = CH2 + KCl + H2O
