  • A student mistakes the formula for a magnetic moment and uses the formula <img alt="\mathrm{\mu=\sqrt{n(n+4)} \mathrm{BM}}" src="/latex-image/?%5Cmathrm%7B%5Cmu%3D%5Csqrt%7Bn%28n&plus;4%29%7D%2

A student mistakes the formula for a magnetic moment and uses the formula \mathrm{\mu=\sqrt{n(n+4)} \mathrm{BM}} for two metal ions X and Y and calculates the magnetic moment to arrive at the same answer 3.46 BM. What X and Y ?

Option: 1

\begin{aligned} & \mathrm{Ti}^{2+}, \mathrm{Cu}^{2+} \\ \end{aligned}


Option: 2

\begin{aligned} & \mathrm{Ti}^{2+}, \mathrm{Co}^{2+} \\ \end{aligned}


Option: 3

\begin{aligned} & \mathrm{Cu}^{2+}, \mathrm{Fe}^{2+} \\ \end{aligned}


Option: 4

\begin{aligned} & \mathrm{Ti}^{2+}, \mathrm{Ni}^{2+} \end{aligned}

Both the metal ions have the same number of unpaired electrons. So, they will show the same Magnetic Moment using any formula.

\therefore Option (4) is the correct answer.
