What is the hybridization and molecular shape of a water molecule ($\text{H}_2\text{O}$)?

Study flashcard from the deck NEET UG High-Yield Review (Biology, Physics, Chemistry).

Answer

$sp^3$ hybridization with a bent (V-shaped) geometry and a bond angle of approximately $104.5^\circ$.

Explanation

Oxygen has two bonding pairs and two lone pairs; lone pair-lone pair repulsion compresses the ideal tetrahedral $109.5^\circ$ angle to $104.5^\circ$.
