Which one of the following does not correctly represent the correct order of the property indicated against it?
$Ti < V < Cr < Mn\,;$ increasing number of oxidation states
$Ti^{3+} < V^{3+} < Cr^{3+} < Mn^{3+}\,\,:$ increasing magnetic moment
$Ti < V < Cr < Mn\,\,:$ increasing melting points
$Ti < V < Mn < Cr \,\,:$ increasing $2^{nd}$ ionization enthalpy
The correct order of decreasing third ionisation enthalpy of $Ti, \,V,\, Cr,\, Mn$ is
In the series $\operatorname{Sc}(Z=21)$ to $\operatorname{Zn}(Z=30)$, the enthalpy of atomisation of zinc is the lowest, i.e.. $126\, kJ\, mol ^{-1}$. Why?
On heating $Mn{(OH)_2}$ with $Pb{O_2}$ and conc. $HN{O_3}$ pink colour is obtained due to the formation of
$Cu^+$ ion is not stable in aqueous solution, due to
Chloro compound of Vanadium has only spin magnetic moment of $1.73\, BM$. This Vanadium chloride has the formula
