Question

Match List-I with List-II and choose the correct matching codes from the choices given.

List I		List II
A	$PC{l}_5$	1	Linear
B	$I{F}_7$	2	pyramidal
C	$H_3{O}^{+}$	3	Trigonal bipyramidal
D	$Cl{O}_2$	4	Tetrahedral
E	$N{H}_4^{+}$	5	Pentagonal bipyramidal
		6	Angular

• A. A-3, B-5, C-2, D-1, E-4
• B. A-3, B-5, C-4, D-1, E-2
• C. A-3, B-5, C-6, D-1, E-2
• D. A-3, B-5, C-2, D-6, E-4
• E. A-3, B-5, C-2, D-4, E-1

Answer 1

Answer: (D)

$PC{l}_5=s{p}^{3}d$ (Trigonal pyramidal)
$I{F}_7=s{p}^3{d}^3$ (Pentagonal bipyramidal)
$H_3{O}^{+}=s{p}^3$ (Pyramidal)
$Cl{O}_2=s{p}^2$
(Angular) bond length are shorter than single bond due to resonance.
$N{H}_4^{+}=s{p}^3$ (Tetrahedral)
