What type of bond and type of overlapping present in N ₂ molecule ?

Options

  1. ASingle bond and s - s overlap
  2. BDouble bond and s - p overlap
  3. CTriple bond and p - p overlap
  4. DDouble bond and p - p overlap

Correct answer

C. Triple bond and p - p overlap

Step-by-step solution

The electronic configuration of a nitrogen atom is 1s^2 2s^2 2p^3 . Each nitrogen atom has three half-filled 2p orbitals ( 2p_x, 2p_y, 2p_z ). To achieve a stable octet configuration, two nitrogen atoms share three pairs of electrons, forming a triple bond ( N N ). The triple bond consists of one bond and two bonds. The bond is formed by the axial overlapping of one set of p orbitals (e.g., 2p_z - 2p_z ), while the two bonds are formed by the lateral overlapping of the remaining two sets of p orbitals (e.g., 2p_x -
