Find out the correct order of repulsive interaction of electron pairs in the following systems. (I) Lone pair - lone pair (II) Lone pair- bond pair (III) Bond pair-bond pair

Options

  1. A(I) > (II) > (III)
  2. B(II) > (I) > (III)
  3. C(III )> (II) > (I)
  4. D(I) > (III) > (II)

Correct answer

A. (I) > (II) > (III)

Step-by-step solution

Repulsive intraction of electron pairs is as follows : The electron pairs place themselve as for apart as possible in the space in order to have minimum force of repulsion. The magnitude of different types of electronic repulsions follows the order given below: (I) Lone pair-lone pair > (II) Lone pair-bond pair > (III) Bond pair-bond pair
