Question

The values of bond energies of single, double and triple bonds are in the order:

• A. C - C > C = C > C $\equiv$ C
• B. C = C > C - C > C $\equiv$ C
• C. C $\equiv$ C > C = C > C - C
• D. C = C > C $\equiv$ C > C - C

Answer 1

The correct option is C C $\equiv$ C > C = C > C - C

We all know that as the number of bonds between two atom increases, the extent of overlap also increases which is further directly proportional to the bond strength. If the bond is strong enough high amount of energy will be requirred to break it. So the correct sequence of bond order is $C\equiv C>C=C>C-C$. So the correct option is C
