32. The dissociation energy of CH4 (g) is 360 kcal mol-1 and that of C6 H6 (g) is 620 kcal mol-1. The C-C bondenergy is(1) 260 kcal mol-1 (2) 180 kcal mol-1(3) 130 kcal mol-1 (4) 80 kcal mol-1 plz give answer it's urgent... |

Answer» We are given dissociated energy of CH4 = 360 Since, has 4 CH bonds.Dissociated energy of 1 CH bond = 360 ÷ 4 = 90 The dissociation energy of = 620 Where has 1 C-C bond and 6 CH bonds. So, we can calculate the dissociated energy of 1 C-C bond by:C-C bond + 6CH bond = 620C-C bond + (6 × 90) = 620C-C bond + 540 = 620C-C bond = 620 - 540 = 80 Explanation: |
