if magnetic mement is 3.83 BM then it contain three unpaired electrons. It means chromium in $+3$ oxidation state so molecular formula is
$\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6} \mathrm{Cl}_{3}$
This formula have following isomers
(a) $\left[\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right] \mathrm{Cl}_{3}:$ react with $\mathrm{AgNO}_{3}$ but does not show geometrical isomerism.
(b) $\left[\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}\right)_{5} \mathrm{Cl}\right] \mathrm{Cl}_{2} \cdot \mathrm{H}_{2} \mathrm{O}$ react with $\mathrm{AgNO}_{3}$ but does not show geometrical isomerism.
(c) $\left[\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}\right)_{4} \mathrm{Cl}_{2}\right] \mathrm{Cl} .2 \mathrm{H}_{2} \mathrm{O}$ react with $\mathrm{AgNO}_{3}$ and show geometrical isomerism.
(d) $\left[\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}\right)_{3} \mathrm{Cl}_{3}\right] .3 \mathrm{H}_{2} \mathrm{O}$ does not react with $\mathrm{AgNO}_{3}$ and show geometrical isomerism.
$\left[\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}\right)_{4} \mathrm{Cl}_{2}\right] \mathrm{Cl} .2 \mathrm{H}_{2} \mathrm{O}$ react with $\mathrm{AgNO}_{3}$ and show geometrical isomerism and it's IUPAC nomenclature is $\quad$ Tetraaquadichlorido chromium (III) Chloride dihydrate.
ટ્રાન્સ$-[Co(en)\left._{2} Cl _{2}\right]^{+}( A )$ અને સિસ$-[Co(en)$ $\left._{2} Cl _{2}\right]^{+}$ $(B).$
તેમના વિશે સાચા વિધાનો ક્યા છે:
સૂચિ $I$ (સંકીણ) | સૂચિ $II$ (સમઘટકતાનો પ્રકાર) |
$A$. $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_5\left(\mathrm{NO}_2\right)\right] \mathrm{Cl}_2$ | $I$. દ્રાવકમિશ્રણ સમધટકતા |
$B$. $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_5\left(\mathrm{SO}_4\right)\right] \mathrm{Br}$ | $II$. બંધન સમધટકતા |
