Which one of the following does not correctly represent the correct order of the property indicated against it

Options

A. Ti lt V lt Cr lt Mn, increasing number of oxidation states
B. `Ti^(3+) lt V^(3+) lt Cr^(3+) lt Mn^(3+)`, increasing magnetic moment
C. Ti lt V lt Cr lt Mn, increasing melting points
D. Ti lt V lt Mn lt Cr , increasing `2^(nd)` ionization enthalpy

Answer

C

Explanation

Maximum MP in 3d series is shown by Cr because of maximum no. of unpaired `e^(-)` and hence maximum extent of `d-d` overlapping.
