The bond order and magnetic property of acetylide ion are same as that of
Options
- AO 2 +
- BN 2 +
- CNO +
- DO 2 -
Correct answer
C. NO +
Step-by-step solution
The bond order of the acetylide ion HC ≡ C - is 3 , indicating a triple bond between the carbon atoms. The acetylide ion consists of two carbon atoms with a triple bond between them and a negative charge. In the triple bond, there are six bonding electrons (two pi bonds and one sigma bond) and zero antibonding electrons. Among the given options NO + will have the same bond order and magnetic property like acetylide ion. Species Bond Order Magnetic moment HC ≡ C - 3 0 O 2 + 2 . 5 3   B . M N 2 + 2 .
