$A$ ${\left[ CoCl \left( NH _3\right)_5\right]^{2+}}$	$I$ $310$
$B$ ${\left[ Co \left( NH _3\right)_6\right]^{3+}}$	$II$ $475$
$C$ ${\left[ Co ( CN )_6\right]^{3-}}$	$III$ $535$
$D$ ${\left[ Cu \left( H _2 O \right)_4\right]^{2+}}$	$IV$ $600$

નીચે આપેલા વિકલ્પોમાંથી સાચો જવાબ પસંદ કરો.

Solution

b

List $I$ (Coordination entity)	List $II$ (Wavelength of light absorbed in $nm$)
$A$ ${\left[ CoCl \left( NH _3\right)_5\right]^{2+}}$	$I$ $535$
$B$ ${\left[ Co \left( NH _3\right)_6\right]^{3+}}$	$II$ $475$
$C$ ${\left[ Co ( CN )_6\right]^{3-}}$	$III$ $310$
$D$ ${\left[ Cu \left( H _2 O \right)_4\right]^{2+}}$	$IV$ $600$

$E =\frac{ hc }{\lambda} \Rightarrow E \propto \frac{1}{\lambda}$

$\Rightarrow \Delta( CFSE ) \propto \frac{1}{\lambda_{\text {absorb }}} \propto \text { strength of ligand. }$

List \(I\) (Coordination entity)	List \(II\) (Wavelength of light absorbed in \(nm\))
\(A\) \({\left[ CoCl \left( NH _3\right)_5\right]^{2+}}\)	\(I\) \(535\)
\(B\) \({\left[ Co \left( NH _3\right)_6\right]^{3+}}\)	\(II\) \(475\)
\(C\) \({\left[ Co ( CN )_6\right]^{3-}}\)	\(III\) \(310\)
\(D\) \({\left[ Cu \left( H _2 O \right)_4\right]^{2+}}\)	\(IV\) \(600\)

સૂચી $-I$	સૂચી $-II$
$A.$ $\mathrm{K}_2\left[\mathrm{Ni}(\mathrm{CN})_4\right]$	$I$ $\mathrm{sp}^3$
$B.$ $\left[\mathrm{Ni}(\mathrm{CO})_4\right]$	$II$ $\mathrm{sp}^3 \mathrm{~d}^2$
$C.$ $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right] \mathrm{Cl}_3$	$III$ $\mathrm{dsp}^2$
$D.$ $\mathrm{Na}_3\left[\mathrm{CoF}_6\right]$	$IV$ $\mathrm{d}^2 \mathrm{sp}^3$
