The volume (in $mL$) of $0.1 \ M$ $AgNO_3$ required for complete precipitation of chloride ions present in $30 \ mL$ of $0.01 \ M$ solution of $[Cr(H_2O)_5Cl]Cl_2$, as silver chloride is close to

The configurations for the complex $[Co(en)(NH_3)_2Br_2]^+$ are shown. Which of the following statements is incorrect?

Match each coordination compound in List-$I$ with an appropriate pair of characteristics from List-$II$ and select the correct answer using the code given below the lists. $\{en = H_2NCH_2CH_2NH_2\}$,atomic numbers:$\{Ti = 22; Cr = 24; Co = 27; Pt = 78\}$

List-$I$	List-$II$
$P$. $[Cr(NH_3)_4Cl_2]Cl$	$1$. Paramagnetic and exhibits ionisation isomerism
$Q$. $[Ti(H_2O)_5Cl](NO_3)_2$	$2$. Diamagnetic and exhibits cis-trans isomerism
$R$. $[Pt(en)(NH_3)Cl]NO_3$	$3$. Paramagnetic and exhibits cis-trans isomerism
$S$. $[Co(NH_3)_4(NO_3)_2]NO_3$	$4$. Diamagnetic and exhibits ionisation isomerism

Match List-$I$ with List-$II$ and select the correct code:

List-$I$	List-$II$
$A$. Ziegler-Natta	$i$. $Fe_4[Fe(CN)_6]_3$
$B$. Brown ring complex	$ii$. $[Fe(H_2O)_5NO]SO_4$
$C$. Prussian Blue	$iii$. $Al(C_2H_5)_3 + TiCl_4$
$D$. Turnbull Blue	$iv$. $Fe_3[Fe(CN)_6]_2$

Correct code is:

The correct statements from the following are:
$A$. The strength of anionic ligands can be explained by crystal field theory.
$B$. Valence bond theory does not give a quantitative interpretation of kinetic stability of coordination compounds.
$C$. The hybridization involved in the formation of $\left[Ni(CN)_4\right]^{2-}$ complex is $dsp^2$.
$D$. The number of possible isomer$(s)$ of $cis-\left[PtCl_2(en)_2\right]^{2+}$ is one.
