In a molecule like BeF2, which has a linear and symmetrical structure, the bond angle is 180°, causing the dipole moments of the bonds to cancel each other. However, the structure of H2O is bent.

1. Bond angle equals 180°
2. Dipole moments cancel out
3. H2O has a bent shape
4. No correct option

Correct answer: H2O has a bent shape

Solution

H2O is angular due to its bent molecular geometry caused by lone pairs on oxygen, which is a key feature of its structure.
