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 states
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 `: ti lt V lt Cr lt Mn ` . The melting points of transition element first increases to a maximum and then fall as atomic number increases Mn, however has abnormally low melting point due to stable configuation and weak intermetallic bonding.
