STANDARD Chemistry Molecular Shapes MCQ Question
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?
lp-lp repulsion is more than lp-bp repulsion.
lp-bp repulsion is more than lp-lp repulsion.
lp-lp repulsion is equal to lp-bp repulsion.
Presence of lone pair does not affect the bond angle.
Correct Answer
Detailed Explanation
In a water molecule, the lone pair-lone pair (lp-lp) repulsion is greater than the lone pair-bond pair (lp-bp) repulsion, causing the bond angle to decrease from the ideal tetrahedral angle.
