Decreasing order of molar conductivity of the following:
(A)

COC{l_3}.6N{H_3}

(B)

COC{l_3}.5N{H_3}

(C)

COC{l_3}.4N{H_3}

(D)

COC{l_3}.3N{H_3}

will be

View answer and explanation

Correct option: A

A > B > C > D

Option A (

A > B > C > D

) is correct because the molar conductivity decreases with a decrease in the number of ions produced in solution, which corresponds to the number of chloride ions outside the coordination sphere.
