The 
The
Show Hint
Lone pairs occupy more space than bond pairs, causing bond angles to decrease.
Updated On: Apr 20, 2026
- valence shell electron pair repulsion theory (VSEPR)
- molecular orbital theory
- presence of hydrogen bond
- electronegativity difference between hydrogen and oxygen atoms

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
VSEPR theory explains molecular shapes based on electron pair repulsion.
Step 2: Detailed Explanation:
O in H\(_2\)O has 2 bond pairs and 2 lone pairs. Lone pair-lone pair repulsion>lone pair-bond pair repulsion, reducing the ideal tetrahedral angle (\(109.5^\circ\)) to \(104.5^\circ\).
Step 3: Final Answer:
Valence shell electron pair repulsion theory (VSEPR).
