Question

The molecule which has T-shaped structure is:

• A. $PCl_{3}$
• B. $ClF_{3}$
• C. $ClF_{3}$
• D. $BCl_{3}$

Answer 1

Answer: (B)

$ClF_{3}$

Answer 2

$C l F_{3}$ has $s p^{3} d$ hybridization. Out of five $s p^{3} d$ hybrid orbitals two are completely filled by $l p$ and three are half filled which overlap with three $2 p_{z}$ half filled orbitals of three $F$-atoms. Due to the presence of two lps its geometry is bent $T$-shaphed.
