Vedclass · Answer

(D) The color observed in a complex is the complementary color of the wavelength absorbed. The relationship between absorbed wavelength $(\lambda_{abs})$ and observed color is: $1$. Blue color observed $\rightarrow$ Orange light absorbed $(\approx 580-620 \ nm)$. $2$. Red color observed $\rightarrow$ Green light absorbed $(\approx 500-560 \ nm)$. $3$. Green color observed $\rightarrow$ Red light absorbed $(\approx 620-750 \ nm)$. Comparing the absorbed wavelengths: $\lambda_{abs}$ for $III$ (Red absorbed) > $\lambda_{abs}$ for $I$ (Orange absorbed) > $\lambda_{abs}$ for $II$ (Green absorbed). Therefore,the correct order is $III > I > II$.

List-$I$ (Complex ion)	List-$II$ (Calculated spin only magnetic moment $(BM)$)
$A$. $[Cr(H_2O)_6]^{2+}$	$I$. $3.87$
$B$. $[Co(H_2O)_6]^{2+}$	$II$. $5.92$
$C$. $[Cu(H_2O)_6]^{2+}$	$III$. $4.90$
$D$. $[Mn(H_2O)_6]^{2+}$	$IV$. $1.73$

Three complex compounds $I$,$II$ and $III$ have Blue,Red and Green colour respectively. Which of the following orders of $\lambda_{abs}$ (absorbed wavelength) is $CORRECT$?
