A-B undergoes homolytic cleavage to form free radicals.change in enthalpy in this case iis +x kj/ mol...n wen A-B goes heterolytic cleavage change in enthalpy is +y kj/mol.. which statement is true; x>y : Y>x :x=y ; depends upon nature of A n B........plz explain wid reasons

Dear anshu,

Answer is X>Y,

because in homolytic cleavage two free radicals are formed from two atoms,and hence more cahnge in enthaly but in hetrolytic cleavage only one free radical is formed which is less change in enthlpy than that of two free radicals
