Q. Bond length depends upon the size of atoms, hybridisation, resonance, bond order etc. In the following relations.
I. Bond length $\propto$ size of atoms
II. Bond length $\propto$ hybridisation (no. of hybrid orbitals)
III. Bond length $\propto$ bond order
Choose the correct option.

Chemical Bonding and Molecular Structure

Solution:

Statements I and II are correct while the statement III is incorrect. It's correct form is as follows :
Bond length is directly proportional to size of atoms and hybridisation but it is inversely proportional to bond order.
Bond length $\propto \frac{1}{\text { bond order }}$
