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

Options

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

Answer

A

Explanation

does not represent the correct order of melting points. The correct order is: TiMn. The melting points of transition elements first increase to a maximum and then fall as atomic number increases. Mn, however, has abnormally low melting point due to stable configuration and weak intermetallic bonding
