Answer 1

Answer:

Explanation:

Bond order of N2 is 3 and that of N+2 is 2.5 .

Greater the bond order , shorter is the bond length

Hence order of NO is 2.5 and that of NO+ is 3 Thus , bond length of NO+ is shorter . Hence ,II is true

Bond order of O2 is 2 while that O2−2 is 1. Thus,

bond length of O2 is shorter . Hence , III is not ture .

Answer 2

Answer:

Bond order of N2 is 3 and that of N+2 is 2.5.

Greater the bond order, shorter is the bond length

Hence order of NO is 2.5 and that of NO+ is 3 Thus, bond length of NO+ is shorter . Hence,Il is true

Bond order of O2 is 2 while that O2-2 is 1. Thus,

bond length of O2 is shorter . Hence, III is not ture.
