Question

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

Solution

Correct option is

73.6%

 

If the EN difference is 1.9, then bond is 50% ionic. The difference in electronegativity is 2.8, therefore, percentage ionic character due to EN difference of 2.8 is
