Concept:A molecule’s shape depends on the repulsion between electron pairs around the central atom, especially lone pairs.
Explanation:The water molecule has one oxygen atom bonded to two hydrogen atoms.
Oxygen has four electron pairs: two bond pairs and two lone pairs.
The two lone pairs repel each other and push the bond pairs closer.
This compresses the bond angle to about
104.5∘.
As a result, the atoms are not arranged in a straight line.
Therefore, the molecule has a bent or angular shape.
Answer:D. V-shaped
