Match the following A) CoCl3.6NH3 (p) 97

Question

Match the following

Column-I Complex (with coordination number of Co3+ as equal to six)	Column-II Maximum molar conductivity (S cm2 mol–1)
(A) CoCl3.6NH3	(p) 97
(B) CoCl3.5NH3	(q) 0
C) CoCl3.4NH3	(r) 404
(D) CoCl3.3NH3	(s) 229

Answer 1

A→(r), B→(s), C→(p), D→(q) 

[Co(NH₃)₆] Cl₃ will give maximum number of ions(4) because of which conductivity is maximum i.e. 404. 

In [Co(NH₃) 3Cl₃] no ions are given 

Hence molar conductivity is zero. 

[Co(NH₃) 5Cl]Cl₂ & [Co(NH₃) 4Cl₂] Cl forms 3 & 2 ions.
