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 2nd 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.
