If the electronegativity difference between two atoms is 2.0, the percentage covalent character of the molecule is :

A

`46%`

B

`72%`

C

`54%`

D

`10%`

Text Solution

Verified by Experts

The correct Answer is:
A
If the electronegativity difference between two atoms is 1.7, then the bond is 50% ionic and 50% covalent. Now, the difference is more than 1.7, it will be slightly more ionic than 50 i.e., 46% covalent or 54% ionic.
