If the electronegativity of A is 2.0 and that of B is 3.0, what is the percentage of the covalent character of the bond A - B?

A

0.805

B

0.9

C

0.46

D

0.54

Text Solution

Verified by Experts

The correct Answer is:
A
The ionic character can be calculated as follows.
`16 (X_A - X_B)+3.5(X_A - X_B)^2 = 16 xx 1 +3.5 xx 1^2`
Therefore, covalent character is 100 – 19.5 = 80.5%.
