Question

T-shape geometry is shown by

• A. XeF$_2$
• B. SO$_2$
• C. IO$_4^-$
• D. BrF$_3$

Hint:

T-shape geometry arises from AX$_3$E$_2$ type molecules. Remember: 5 electron pairs → 2 lone pairs in equatorial positions → T-shape.

Answer 1

The Correct Option is D

Step 1: Use VSEPR theory.
T-shape geometry corresponds to AX$_3$E$_2$ type molecule.
This means 5 electron pairs (trigonal bipyramidal arrangement) with 2 lone pairs occupying equatorial positions.
Step 2: Analyze each option.
(A) XeF$_2$ → AX$_2$E$_3$ → Linear geometry.
(B) SO$_2$ → AX$_2$E → Bent geometry.
(C) IO$_4^-$ → AX$_4$ → Tetrahedral geometry.
(D) BrF$_3$ → AX$_3$E$_2$ → Trigonal bipyramidal electron geometry with 2 lone pairs → T-shaped molecular geometry.
Step 3: Conclusion.
Therefore, BrF$_3$ shows T-shaped geometry.
