Consider the following reactions of complex compounds A,B and C
(i) `CoCl_(2)Br*5NH_(3) +excess" "Ag^(+)(aq)to1AgCl(s)`
(ii) `underset("Compound B")(CoCl_(2)Br*5NH_(3))+"excess "Ag^(+)(aq) to 2AgCl(s)`
(iii) `underset("Compound C")(CoCl_(2)Br*4NH_3)+"excess "Ag^(+)(aq.) to 1AgCl(s)`
Then according to the given information the correct statement(s) is/are:

Options

A. Compounds(A) and (B) are ionisation isomers
B. Molar conductivity of compounds (A) and (B) are almost same
C. Compounds (A), (B) and (C) do not exhibit geometrical isomerism
D. Order of CFSE values, `Delta_(0)(A) gt Delta_(0)(B) gt Delta_(0)(C)`

Answer

A, B, D

Explanation

A:`[CoCl(NH_(3))_(5)]*BrCl`
`B:[CoBr(NH_(3))_(5)]*Cl_(2)`
`C:[CoBrCl(NH_(3))_(4)]*Cl`
