Question

The factors that affect the bond length are:

• A. Size of the atom
• B. Hybridization
• C. Bond Order
• D. All of the above

Answer 1

The correct option is D All of the above

$\left(a\right)$ Smaller the size of the atom, smaller is the covalent radius and hence smaller the covalent bond.
$\left(b\right)$ Greater the s-character, more bulky the orbitals and hence smaller the bond length.
$\left(c\right)$ Greater the bond order, smaller the bond length. Triple bond is shorter than a double bond and a double bond is shorter than a single bond.
Hence, all the statements are correct.
