Question

Consider the following complexes:
(I) `K_(2)Ptcl_(6)` (II) `PtCl_(4).2NH_(3)`
(III) `PtCl_(4).3NH_(3)` (IV) `PtCl_(4).5NH_(3)`
Their electrical conductances in an aqueous solution are:
A. 256,0,97,404
B. 404,0,97,256
C. 256,97,0,404
D. 404,97,256,0

Answer 1

Correct Answer - A
Greater the number of ions , greater the conductance
1. `K_(2) [Pt Cl_(6)]hArr ubrace(2K^(+)+[PtCl_(6)]^(2-))_("three ion ")`
`2. Pt Cl_(4) .2NH_(3)hArr [Pt(NH_(3))_(2)Cl_(4)]to ` no ion ( least )
`3.[Pt(NH_(3))_(3)Cl hArr ` two ions
4. ` [Pt(NH_(3))_(5)Cl]Cl_(3)hArr ` four ions (maximum ) hence ,(a) is correct
