Concept:Water has a bent (V-shaped) molecular geometry due to two lone pairs on oxygen, and its bond angle is less than the ideal tetrahedral angle.
Explanation:Oxygen in water forms two sigma bonds with hydrogen atoms.
It also has two lone pairs of electrons.
These four electron pairs arrange tetrahedrally around oxygen.
Lone pairs repel more strongly than bonding pairs.
This compresses the H–O–H bond angle from the ideal
109.5∘.
The actual bond angle in water is approximately
104.5∘, usually quoted as
105∘.
Therefore, the molecular shape is bent and the bond angle is
105∘.
Answer:D. bent,
105∘
