Given: C 2 H 6( g ) longrightarrow 2 C ( g )+6 H ( g ) ; Δ H=712 kcal The C-C bond energy is 112 kcal, what is the C-H bond energy? (A) 88 kcal (B) 12 kcal (C) 50 kcal (D) 100 kcal

Tardigrade Admin · Accepted Answer

Bond energy of 6 C - H bonds = 712 - 112 = 600 kcal

Q. Given : $C_{2} H_{6 (g)} ⟶ 2 C_{(g)} + 6 H_{(g)}; Δ H = 712 k c a l$ The $C - C$ bond energy is $112 k c a l$ , what is the $C - H$ bond energy?

$88 k c a l$

$12 k c a l$

$50 k c a l$

$100 k c a l$

Bond energy of $6 C - H$ bonds $= 712 - 112 = 600 k c a l$
