,and
which
is more easily hydrolysed by aqueous KOH? Give
reason.
[2]
Or
The treatment of alkyl chlorides with aqueous KOH leads to
the formation of alcohols, but in presence of alcoholic KOH, alkenes are major
products. Explain. [2]
Answer:
is
hydrolysed to a greater extent as compared to
[1]
This is more stable due to resonance because of
delocalization of 
-electrons
in two benzene ring.
Or
Aqueous KOH is a strong base ionising completely and thus
releasing free 
ions.
This displace halogen from alkyl halides in 
reaction.
[1]
When alcoholic KOH is taken, then alkoxide 
is formed.
is a
stronger base than 
and
causes dehvdrohalogenation (loss of H X) from alkyl halide.
