Question

arrange homolytic bond energies of c-h bond designated by 1 2 3 4​

Answer 1

Answer:

Correct option is

C

z>y>x

Bond dissociation energy in hamolytic cleavage is directly  prpoprtional to the bond strength as z→sp2 hybridised → more strong than y and x

y→ having partial sp2 character because of hyperconjugation.

x→ No hyperconjugation, purely sp3→ weakest bond.

Bond dissociation energy order is

z>y>x
