Single Choice

The correct sequence of bond length in a single bond, a double bond and triple bond of $$C$$ is:

A$${(C - C) = (C = C) = (C \equiv C)}$$
B$${C \equiv C < C = C < C - C}$$
Correct Answer
C$$C - C < C = C < C \equiv C$$
D$$C = C < C \equiv C < C - C$$

Solution

The bond length changes with the bond order like this:-
$$Bond\ length\ \alpha \ \dfrac { 1 }{ Bond\ order } \ \alpha \ \dfrac { 1 }{ No.\ of\ bonds }$$

As the number of bonds will increase, the bond order will increase and the bond length will decrease.
So, the correct option is $$B$$
$${C \equiv C < C = C < C - C}$$
