Solution

The correct option is A $[C o {({N H}_{3})}_{6}] {C l}_{3}$
More the no. of Ions; more is the molar conductance.
So Option A is correct $[C o {(N H_{3})}_{6}] C l_{3} \to 3 C I^{-} + {[C o {(N H_{3})}_{6}]}^{3 +}$

Which of the following shows maximum molar conductance?

The correct option is A [Co(NH3)6]Cl3More the no. of Ions; more is the molar conductance.So Option A is correct [Co(NH3)6]Cl3→3CI−+[Co(NH3)6]3+

The correct option is A $[C o {({N H}_{3})}_{6}] {C l}_{3}$
More the no. of Ions; more is the molar conductance.
So Option A is correct $[C o {(N H_{3})}_{6}] C l_{3} \to 3 C I^{-} + {[C o {(N H_{3})}_{6}]}^{3 +}$
