The decreasing order of bond dissociation energies of C-C,C-H and H -H bonds is

Options

A. H-Hgt-C-Hgt-C-C
B. -C-Crarr-C-HgtH-H
C. -C-Hgt-C-CrarrH-H
D. -C-CrarrH-Hgt-C-H

Answer

A

Explanation

The bond dissociation energies of H - H C - H and -C-C-bond are 432, 413 and 347 kJ/mole respectively: Therefore the order is,H-H>-C-H>-C-
