24.
anti markinikove rule means
Br should add to the alken ewhich is at least substituted side.
so
option E is correct answer
25.
answer is option B wilkinson catalyst
Homogenious catalyst means that particular catalyst should soluble in reaction mixture
all metal catalysts are heterogenious they will soluble in reaction mixture except wilkin son catalyst.
