	P		Q
a	[Cu(NH3)4]2+	i	Tetrahedral
b	[Ag(NH3)2]+	ii	Octahedral
c	Fe(CO)5	iii	Square planar
d	[Cr(H2O)6]3+	iv	Triagonal bipyramidal
e	[NiCl4]2-	v	Linear

• A. a)-(ii);b)-(iii);c)-(i);d)-(iv);e)-(v)
• B. a)-(iii);b)-(v);c)-(iv);d)-(ii);e)-(i)
• C. a)-(iv);b)-(iii);c)-(v);d)-(i);e)-(ii)
• D. a)-(v);b)-(iv);c)-(ii);d)-(iii);e)-(i)
• E. a)-(iv);b)-(ii);c)-(iii);d)-(v);e)-(i)

Answer 1

The Correct Option is B

Complex Geometry Matching:

a) [Cu(NH₃)₄]²⁺:

• Cu²⁺ typically forms square planar complexes
• Matches with (iii) Square planar

 

b) [Ag(NH₃)₂]⁺:

• Linear geometry (coordination number 2)
• Matches with (v) Linear

 

c) Fe(CO)₅:

• Trigonal bipyramidal geometry
• Matches with (iv) Trigonal bipyramidal

 

d) [Cr(H₂O)₆]³⁺:

• Octahedral geometry (coordination number 6)
• Matches with (ii) Octahedral

 

e) [NiCl₄]^2-:

• Tetrahedral geometry (with weak field Cl^- ligands)
• Matches with (i) Tetrahedral

 

Correct Matching: a-(iii), b-(v), c-(iv), d-(ii), e-(i)

Thus, the correct option is (B): a) - (iii); b) - (v); c) - (iv); d) - (ii); e) - (i).
