Question

Match the columns (formulation of cobalt III chloride ammonia complexes) and choose the correct option from the codes given below.

Column I(Colour)		Column II(Formula)		Column III(Solution conductivity corresponds to)
A.	Yellow	1.	$\left[ Co \left( NH _{3}\right)_{6}\right]^{3+} 3 Cl ^{-}$	I.	$1: 2$ electrolyte
B.	Green	2.	$\left[ CoCl \left( NH _{3}\right)_{5}\right]^{2+} 2 Cl ^{-}$	II.	$1: 1$ electrolyte
C.	Purple	3.	$\left[ CoCl _{2}\left( NH _{3}\right)_{4}\right]^{+} Cl ^{-}$	III.	$1: 3$ electrolyte

• A. $A-2(I), B-1(II), C-3(III)$
• B. $A-3(II), B-2(III), C-1(I)$
• C. $A-1(III), B-3(II), C-2(I)$
• D. $A-2(III), B-3(I), C-1(II)$

Answer 1

Answer: (C)

$A \rightarrow 1(III) ; B \rightarrow 3(II) ; C \rightarrow 2(I)$
