Which of the following cleavage of bond can result in Homolytic Cleavage?
Which of the following cleavage of bond can result in Homolytic Cleavage?
The correct options are
A
B
What do you mean by Homolytic Cleavage?
Homolytic Fission:
Occurs in gas phase or in non-polar solvents and is catalysed by reagents. In such fission free radicals are formed. Here the bond pair is equally shared after the fission.
AB → A0 + B0 (free radicals)
Condition for Homolytic Bond Fission : Homolysis takes place in the presence of peroxide, UV light, heat (≥ 500∘C), electricity and free radical. The process is known as initiation of free radical reaction.
A:B (i)Peroxide−−−−−−−−−→ A0+B0
(ii) hv
(iii) Δ
(iv) Electricity or
(v) Free radical
CH3 − H hv−→ .CH3↓ + .H
methyl free radical
So, one of the necessary condition is:
It should be non - polar.
⇒ If there will electronegative difference, the compound will be polar.
In Cl − Cl and CH3−H, they both are non polar, hence Homolytic fission.
