F3 Teaching Savita 30-1-24 D2

Explanation:-

The C-I bond is longer due large size of the iodine compare to Cl in chlorofom

F3 Teaching Savita 30-1-24 D3

The Cl-H are in proxmity such that they will experience more e-e repulsion so the hydrogen angle deviation is more in case of Cl-H bond in chlorofom.

Conclusion:-

Hence, the out-of-plane C-H wags in iodoform and chloroform would respectively correspond to the potential energy surfaces A and B
