. The orbital overlapping is maximum in
- To explain these we have to remember that P orbital has more directional nature and as orbital has non directional nature. So the P orbital has more effective overlap then that of the S orbital.
- In the case of Cl2 there is an overlap between two P orbital, therefore the overlap is more effective and maximum overlap.
- But in case of Hl, HCl, HBr the overlap between the S orbital of hydrogen and P orbital of halogen . So overlap is not that effective and minimum overlap.
Correct Optionis: (A) Cl2
