Question

Increasing order of carbon-carbon bond length for the following is $\underset{(A)}{C_2H_4}\,\, \underset{(B)}{C_2H_2}\,\, \underset{(C)}{C_6H_6}\,\, \underset{(D)}{C_2H_6}$

• A. B < C < A < D
• B. C < B < A < D
• C. B < A < C < D
• D. D < C < A < B

Answer 1

Answer: (C)

B < A < C < D

Answer 2

The correct option is(C): B < A < C < D.

In $C _{2} H _{6}$, carbon-carbon bond is single $(1.54\, ?)$. In $C _{6} H _{6}$, carbon-carbon bond is partially double $(1.39\, ?)$

In $C _{2} H _{4}$, carbon-carbon bond is double $(1.34\, ?)$

In $C _{2} H _{2}$, carbon-carbon bond is triple $(1.10\, ?)$.
