If enthalpy of dissociation of CH 4 and C 2 H 6 are 320 and 600 calories respectively then bond energy of C–C bond is :
Text Solution
Verified by ExpertsThe correct answer is:
D
CH 4 ⎯→ C + 4H
Δ H = 320 = Δ H C–H ; Δ H C–H = 80
C 2 H 6 ⎯→ 2C + 6H
Δ H = 600 = Δ H C–C + 6 Δ H C–H
600 = Δ H C–C + 6 × 80
Δ H C–C = 120 cal
