Which of the following shows maximum magnetic moment?
Options
- AMg 2 +
- BTi 3 +
- CV 3 +
- DFe 2 +
Correct answer
D. Fe 2 +
Step-by-step solution
More be the number of unpaired electrons → more be the magnetic moment. and Number of unpaired electrons in Mg 2 + = 0 Number of unpaired electrons in Ti 3 + = 1 Number of unpaired electrons in V 3 + = 2 Fe 2 + = 4 Number of unpaired electrons in Thus, Fe 2 + show maximum value of magnetic moment ( μ ) . also, μ = n ( n + 2 ) . BM ( n = Number of unpaired electrons).
