Question

Shape of H\(_2\)O molecule is:

• A. Linear.
• B. Bent or V-shaped.
• C. Trigonal planar.
• D. Tetrahedral.

Hint:

The bent shape of H\(_2\)O is due to the lone pairs on the oxygen atom, which push the hydrogen atoms closer together.

Answer 1

The Correct Option is B

Step 1: Understanding molecular geometry.
The H\(_2\)O molecule consists of two hydrogen atoms covalently bonded to a central oxygen atom. The oxygen atom has two lone pairs of electrons, which cause the molecule to adopt a bent or V-shape. Step 2: Explanation of the shape.
The lone pairs on oxygen repel the bonding pairs of electrons, which forces the molecule to adopt a bent geometry. The bond angle is approximately 104.5°, which is less than the ideal tetrahedral angle of 109.5° due to the lone pair repulsion. Step 3: Conclusion.
Thus, the shape of the H\(_2\)O molecule is bent or V-shaped.
