Bond order is defined as the number of bonds between two atoms in a molecule. In dinitrogen, there are two nitrogen atoms which are bonded together by a triple bond (a sigma bond and two pi bonds). The bond order is calculated as [(number of bonding electrons) - (number of anti-bonding electrons)]/2. In the case of dinitrogen, there are 10 bonding electrons and 4 anti-bonding electrons, giving a bond order of 2.

Incorrect options

1) The bond order of a single bond is 1, but dinitrogen has a triple bond between the two nitrogen atoms.

3) The bond order of a triple bond is 3, but this answer is incorrect because dinitrogen actually has a bond order of 2.

4) The maximum bond order that two atoms can have is 3 (corresponding to a triple bond), so this answer is incorrect.
