QJEEM02Chd048: JEE Main 2002 Chemistry - Class 12 JEEM02Chd048 Solution: Which of the following ions has the maximum magnetic moment?

Which of the following ions has the maximum magnetic moment?

Multiple Choice Options

  • A Mn2+
  • B Fe2+
  • C Ti2+
  • D Cr2+

Step-by-Step Verified Solution

Mn++−5  M{n^{ + + }} - 5\,\, unpaired electrons

Fe++−4  F{e^{ + + }} - 4\,\, unpaired electrons

Ti++T{i^{ + + }} −2  - 2\,\, unpaired electrons

Cr++−4  C{r^{ + + }} - 4\,\, unpaired electrons

hence maximum no. of unpaired electron is present in Mn++.M{n^{ + + }}.

NOTE : Magnetic moment ∝\propto number of unpaired electrons
