Which of the following statements are correct

Options

A. If an electron is removed by oxidising NO, the nitrosonium ion `NO^(+)` is formed
B. In `NO^(+)` , the bond order is 3.0
C. The N - O bond length contracts form 1.15A in NO to 1.06A in `NO^(+)`
D. NO is coloured gas the presence of an unpaired electron

Explanation

`{:("Bond order"=(10.5)/2=2.5,"Bond order"=(10.4)/2=3),(1.15A^(0),1.06A^(0)):}" "( :. "B and lengh " alpha 1/("Bond order"))`
