Question

A molecule has a T-shape. The total number of electron pairs in the valence shell of its central atom is:

• A. \( 4 \)
• B. \( 5 \)
• C. \( 6 \)
• D. \( 3 \)

Hint:

A T-shaped molecular geometry occurs when the central atom has 5 electron pairs, with two lone pairs causing angular distortion.

Answer 1

The Correct Option is B

Step 1: Understanding Molecular Geometry A T-shaped molecule forms when: - The central atom has 5 electron pairs, but only three are bonding pairs. - The remaining two are lone pairs, distorting the molecular shape. Step 2: Example of a T-Shaped Molecule A common example is ClF\(_3\) (Chlorine trifluoride). The central atom (Cl) has five electron pairs: - Three bonding pairs (with fluorine atoms). - Two lone pairs, causing repulsion and leading to the T-shape. Conclusion Thus, the correct answer is: \[ 5 \]
