Question

The HF bond length is 92 pm, 16% shorter than the sum ofthe covalent radii of H (37 pm) and F (72 pm). Suggest a reasonfor this difference. Similar calculations show that the differencebecomes smaller down the group from HF to HI. Explain.

Expert Solution

Step 1

During formation of covalent bond orbitals are merged partially for overlapping between the bonded atoms and the bond length is shorter than the sum of the covalent radii of the atoms.

For H-F molecule, overlapping is more effective because of less difference of size of orbitals than H-Cl , H-Br and H-I so, the difference becomes smaller down the group from HF to HI.
