A) \[A>B>C\]
B) \[B>A>C\]
C) \[C>B>A\]
D) \[C>A>B\]
Correct Answer: A
Solution :
Bond length \[\propto \frac{1}{Bond\text{ }order}\] Bond length decreases on increasing bond order \[\underset{\begin{smallmatrix} \,\,\,\,\,\,\,\,\,\,\,\,\,\,ethane \\ Bond\text{ }order=1 \end{smallmatrix}}{\mathop{{{H}_{3}}C-C{{H}_{3}}}}\,>\underset{\begin{smallmatrix} \,\,\,\,\,\,\,\,\,\,\,\,\,\,ethene \\ Bond\text{ }order=2 \end{smallmatrix}}{\mathop{{{H}_{2}}C=C{{H}_{2}}}}\,>\underset{\begin{smallmatrix} \,\,\,\,\,\,\,\,\,\,\,\,\,\,ethyne \\ Bond\text{ }order=3 \end{smallmatrix}}{\mathop{H-C\equiv C-H}}\,\]You need to login to perform this action.
