The shape of water molecule, which should be tetrahedral has a bent or distorted tetrahedral shape with a bond angle 104.5 ° . What could be the reason for this?

Options

  1. Alp-lp repulsion is more than lp-bp repulsion
  2. Blp-bp repulsion is more than lp-lp repulsion
  3. Clp-lp repulsion is equal to lp-bp repulsion
  4. Dpresence of lone pair does not affect the bond angle

Correct answer

A. lp-lp repulsion is more than lp-bp repulsion

Step-by-step solution

Due to presence of lone pairs, the repulsion is more which changes the bond angle to 104.5 ° .
