Question

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

List I		List II
A	$PCl_5$	1	Linear
B	$IF_7$	2	pyramidal
C	$H_3O^+$	3	Trigonal bipyramidal
D	$ClO_2$	4	Tetrahedral
E	$NH_4^+$	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.
$ NH_{4}^{+}=s{{p}^{3}} $ (Tetrahedral)
