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? (A) lp-lp repulsion is more than lp-bp repulsion (B) lp-bp repulsion is more than lp-lp repulsion (C) lp-lp repulsion is equal to lp-bp repulsion (D) presence of lone pair does not affect the bond angle

Tardigrade Admin · Accepted Answer

Due to presence of lone pairs, the repulsion is more which changes the bond angle to 104.5° . <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-eoypwritnqkt.png" />

Q. The shape of water molecule, which should be tetrahedral has a bent or distorted tetrahedral shape with a bond angle $104. 5^{\circ} .$ 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

Due to presence of lone pairs, the repulsion is more which changes the bond angle to $104. 5^{\circ} .$
