Question

the dissociation energy of CH4(g) is360 Kcal/mol & that of C2H6 (g) is 620 Kcal/mol the C-C bond energy is​

Answer 1

Answer:

80 Kcal/mol

Explanation:

4C-C = 360

C-C = 90

C-C + 6C-H = 620

C-C = 620 - 6C-H

=620 - 6(90) = 620 - 540 = 80

Answer 2

Explanation:

In ch4 there are 4 c-h bonds

For 1c-h bond energy is 360/4=90

In c2h6 there is one c-c and 6 c-h bonds

So c-c+6*90=620

C-c=80

C-c bond energy is 80kcal/mol
