QAIPM-2012-Ch-1623: NEET 2012 Chemistry - Class 12 AIPM-2012-Ch-1623 Solution: Which one of the following does not correctly represent the…

Which one of the following does not correctly represent the correct order of the property indicated against it? Ti < V < Cr < Mn; increasing number of oxidation states Ti3+<V3+<Cr3+<Mn3+Ti^{3+} < V^{3+} < Cr^{3+} < Mn^{3+}: increasing magnetic moment Ti < V < Cr < Mn: increasing melting points Ti < V < Mn < Cr: increasing 2nd ionization enthalpy

Multiple Choice Options

  • A Ti < V < Cr < Mn; increasing number of oxidation states
  • B Ti 3+ < V 3+ < Cr 3+ < Mn 3+ : increasing magnetic moment
  • C Ti < V < Cr < Mn : increasing melting points
  • D Ti < V < Mn < Cr : increasing 2 nd ionization enthalpy

Step-by-Step Verified Solution

The melting points of the transition elements first rise to a maximum and then fall as the atomic number increases, manganese have abnormally low melting points.
