JEE MAIN - Chemistry (2022 - 27th July Evening Shift - No. 20)
The spin only magnetic moment of the complex present in Fehling's reagent is __________ B.M. (Nearest integer).
Answer
2
Explanation
In the complex present in Fehling's reagent, $\mathrm{Cu}^{+2}$ ion is present.
So, spin only magnetic moment
$$ =\sqrt{1(1+2)} $$
$$ \begin{aligned} & =\sqrt{3} \simeq 2 \mathrm{~B} . \mathrm{M} \end{aligned} $$
So, spin only magnetic moment
$$ =\sqrt{1(1+2)} $$
$$ \begin{aligned} & =\sqrt{3} \simeq 2 \mathrm{~B} . \mathrm{M} \end{aligned} $$
