Text Solution

Verified by Experts
The correct answer is:
A

a. As ability to gain electron increases oxidising property increases. Here, F is the most electronegative element having highest value of SRP hence it has highest oxidising power.

This is the incorrect order of ionic character of metal halide.
Correct order can be written as

As electronegativity difference between metal and halogen increases, ionic character increases.
c.

This is incorrect order of bond dissociation energy. Correct order is due to electronic repulsion among lone pairs in molecule.
d.

As the size of the halogen atom increases, the halogen hydrogen bond strength decreases.
