Solution
The correct option is BIV<III<II<I In octahedral complexes, metal is coordinated with 6 ligands. No. of ion given by complexes- I - 4 ion (one complex ion + 3 chloride ion) II - 3 ion (one complex ion + 2 chloride ion) III - 2 ion (one complex ion + 1 chloride ion) IV - no ion. So molar conductance order is I > II > III > IV
