Arrange the bonds in order of increasing ionic character in the molecules. LiF , K 2 O , N 2 , SO 2 and ClF 3 .
Options
- AClF 3 < N 2 < SO 2 < K 2 O < LiF
- BLiF < K 2 O < ClF 3 < SO 2 < N 2
- CN 2 < SO 2 < ClF 3 < K 2 O < LiF
- DN 2 < ClF 3 < SO 2 < K 2 O < LiF
Correct answer
C. N 2 < SO 2 < ClF 3 < K 2 O < LiF
Step-by-step solution
The ionic character in a molecule is dependent upon the electronegativity difference between the constituting atoms. The greater the difference, the greater will be the ionic character of the molecule. N 2 < SO 2 < ClF 3 < K 2 O < LiF The Ionic character depends upon the difference in electronegativity (bond polarity). N 2 is a covalent molecule & the difference in electrongegativities are: |X S – X 0 | = 1 . 0 |X Cl – X F | = 1 . 0 |X K – X 0 | = 2 . 6 |X Li – X F | = 3 . 5
