Which of the following molecules has trigonal planar geometry?

Options

(a) BF₃
(b) NH₃
(c) PH₃
(d) IF₃

Correct Answer:

BF₃

Explanation:

(a) BF₃ ⇒ 3bp + 0/p ⇒ sp³ -hybridisation and triagonal planar geometry.
(b) NH₃ ⇒ 3bp + 1/p ⇒ sp³ -hybridisation and pyraminal geometry.
(c) PH₃ ⇒ 3bp + 1/p ⇒ sp³ -hybridisation and pyraminal geometry.
(d) IF₃ ⇒ 3bp + 2/p ⇒ sp³d -hybridisation and T shape.
