Match the bond order for the following molecules. The correct answer is

Options

  1. A(a)
  2. B(b)
  3. C(c)
  4. D(d)

Correct answer

B. (b)

Step-by-step solution

Bond order the number of chemical bonds between a pair of atom. So, (B.O) aligned & Li ₂= Li - Li (1) & N ₂= N N (3) & Be ₂= Be Be ( No bond) (0) & O ₂= O = O aligned Note Zero bond order means the molecule is too unstable and so it will not exist. Electrons will fill according to the energy levels of the orbitals.
