1.	The bond dissociation energy of methane and ethane are 360 kJ "mol"^(-1) and 620 kJ "mol"^(-1) respectively. Then, the bond dissociation energy of C-C bond is _____
Answer» `170 KJ "mol"^(-1)` `50 KJ "mol"^(-1)` `80 KJ "mol"^(-1)` `220 KJ "mol"^(-1)` Solution :4(C-H)is equal to 360KJ/mol (C-H) is equal to 90 KJ/mol
