Question

Identify the $T$-shaped molecule in the following

• A. $BF_3$
• B. $NH_3$
• C. $NF_3$
• D. $CIF_3$

Answer 1

Answer: (D)

$CIF_3$

Answer 2

For a T-shape molecule, its

central-atom must contain 3 sigma $(\sigma)$ bonds $(b p)$ and 'wo lone pairs ( $1 p$ ) of electrons.

(a) $BF_{3} \to bp=3 lp=0$

(b) $NH_{3} \to bp =3,lp=1$

(c) $NF_{3} \to bp =3,lp=1$

(d) $CiF_{3} \to bp =3,lp=2$

(e) $PCl_{3} \to bp =3, lp=1$
