Question

The incorrectly matched pair, among the following is

1	Molecule	Shape
a	$BrF_{5}$	Trigonal bipyramidal
b	$SF_{4}$	See saw
c	$ClF_{3}$	T-shape
d	$NH^{+}_{4}$	Tetrahedral
e	$NH_{3}$	Trigonal pyramidal

• A. a
• B. b
• C. c
• D. d
• E. e

Answer 1

Answer: (A)

$ BrF _{5}=5 b p+1 l p \Rightarrow $ square pyramidal

$ SF _{4}=4 b p+1 l p \Rightarrow $ see saw

$ClF _{3}=3 b p+2 l p \Rightarrow $ T -shape

$ NH _{4}^{+}=4 b p+0 l p \Rightarrow $ tetrahedral

$ NH _{3}=3 b p+1 l p \Rightarrow $ trigonal pyramidal
