The electronegativity values of atoms A ...

The electronegativity values of atoms A and B are 1.8 and 4.0 respectively. The percentage of covalent character of A-B bond is :

A

`50%`

B

`27.8%`

C

`47%`

D

`56.2%`

Text Solution

Verified by Experts

The correct Answer is:
B
Since electronegativity difference is more from 1.7, the bond will be more ionic than 50% covalent.
