Nitrogen N2 molecule has 3 unpaired electron on each atom therefore it shows three bond that are?
Correct answer: B. 1 sigma & 2 pi bond
- A. 2 sigma & 1 pi bond.
- B. 1 sigma & 2 pi bond
- C. 3 sigma
- D. 3 pi bond
Explanation
Correct option is B. A pair of atoms may be connected by one or by two pi bonds only if a sigma bond also exists between them; in the molecule of nitrogen (N2), for example, the triple bond between the two nitrogen atoms comprises a sigma bond and two pi bonds.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
