Question:
Identify the T-shaped molecule in the following
Identify the T-shaped molecule in the following
Show Hint
AX$_3$E$_2$ → always T-shaped.
Updated On: May 2, 2026
- BF$_3$
- NH$_3$
- NF$_3$
- ClF$_3$
- PCl$_3$
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept: VSEPR theory
---
Step 1: T-shaped geometry
Occurs when: \[ AX_3E_2 \] ---
Step 2: Analyze ClF$_3$
• Central Cl has 5 electron pairs
• 3 bond pairs + 2 lone pairs Geometry → T-shaped ---
Step 3: Other options
• BF$_3$ → trigonal planar ❌
• NH$_3$ → pyramidal ❌
• NF$_3$ → pyramidal ❌
• PCl$_3$ → pyramidal ❌ --- Final Answer: \[ \boxed{\text{ClF}_3} \]
