4. d and f- block elements — Chemistry STD 12 Science — Question

$A + H_2O + CO_2 \to B$

$B + NaCl \to C + NH_4Cl$

$C\xrightarrow{\Delta }D + {H_2}O + C{O_2}$

Incorrect statement is

Statement I : $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]^{3+}$ is a homoleptic complex whereas $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+}$is a heteroleptic complex.

Statement II : Complex $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]^{3+}$ has only one kind of ligands but $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+}$has more than one kind of ligands.

In the light of the above statements, choose the correct answer from the options given below.

$1.$ $P$ and $Q$, respectively, are the sodium salts of

$(A)$ hypochlorus and chloric acids

$(B)$ hypochlorus and chlorus acids

$(C)$ chloric and perchloric acids

$(D)$ chloric and hypochlorus acids

$2.$ $R , S$ and $T$, respectively, are

$(A)$ $SO _2 Cl _2, PCl _5$ and $H _3 PO _4$

$(B)$ $SO _2 Cl _2, PCl _3$ and $H _3 PO _3$

$(C)$ $SOCl _2, PCl _3$ and $H _3 PO _2$

$(D)$ $SOCl _2, PCl _5$ and $H _3 PO _4$

Give the answer question $1$ and $2.$
