A) more in ethane
B) more in ethane
C) more in ethyne
D) same in all these
Correct Answer: C
Solution :
\[H\text{ }\underset{|}{\overset{|}{\mathop{C}}}\,<=\overset{|}{\mathop{C}}\,H<\equiv CH\] Bond energy \[411~~\,\,\,\,\,\,\,~444.14\text{ }\,\,\,\,\,\,\,\,506.96\text{ }Jmo{{l}^{-1}}\] So, the\[C-H\]bond energy is more in ethyne.
