The compound which does not show paramagnetism is :-
$[Cu(NH_3)_4]Cl_2$
$[Ag(NH_3)_2]Cl$
$NO$
$NO_2$
What can be inferred from the magnetic moment values of the following complex species?
Example | Magnetic Moment $(BM)$ |
$K _{4}\left[ Mn ( CN )_{6}\right.$ | $2.2$ |
$\left[ Fe \left( H _{2} O \right)_{6}\right]^{2+}$ | $5.3$ |
$K _{2}\left[ MnCl _{4}\right]$ | $5.9$ |
The melting point of $Zn$ is lower as compared to those of the other elements of $3d$ series because
Although $\mathrm{Cr}^{3+}$ and $\mathrm{Co}^{2+}$ ions have same number of unpaired electrons but the magnetic moment of $\mathrm{Cr}^{3+}$ is $3.87$ $B.M.$ and that of $\mathrm{Co}^{2+}$ is $4.87$ $B.M.$ Why ?
Which one of the following species is stable in aqueous solution ?
Which of the following ions is coloured
