The values of electronegativity of atom A and B are 1.20 and 4.0 respectively. The percentage of ionic character of A-B bond is nearly

A

0.5

B

0.7224

C

0.553

D

0.42

Text Solution

Verified by Experts

The correct Answer is:
B
% of ionic character
`=16(x_A - x_B) + 3.5 (x_A - x_B)^2`
`=16(2.8) + 3.5 (2.8)^2`
`=44.8 + 27.44 = 72.24`
