Question

Molecular formulae and shapes of some molecules are given below. Choose the incorrect match Formula Shape A NH3 Trigonal pyramidal B SF4 Tetrahedral C ClF4 T - shaped D PCl5 Trigonal bipyramidal E BF3 Trigonal planar (A) A (B) B (C) C (D) D

Tardigrade Admin · Accepted Answer

NH 3 ⇒ 3 b p+1 l p= trigonal pyramidal SF 4 ⇒ 4 bp+1 l p ⇒ see-saw shape ClF 5 ⇒ 3 b p+2 l p ⇒ T -shaped PCl 5 ⇒ 5 b p+0 l p ⇒ trigonal bipyramidal BF 3 ⇒ 3 b p+0 l p ⇒ trigonal planar Thus, the given shape of S F4 is incorrect.

	Formula	Shape
A	$N H_{3}$	Trigonal pyramidal
B	$S F_{4}$	Tetrahedral
C	$Cl F_{4}$	T - shaped
D	$PC l_{5}$	Trigonal bipyramidal
E	$B F_{3}$	Trigonal planar
