Question

The shortest bond would be present in which of the following substances?

• A. I$_2$
• B. CO
• C. CCl$_4$
• D. O$_2$

Hint:

For molecules with multiple bonds, the bond length becomes shorter with an increase in bond order.

Answer 1

The Correct Option is B

In general, the bond length decreases as the bond order increases. The shortest bond length is found in CO because it has a triple bond, which results in a shorter bond compared to the others.
