Answer

Correct option: D.
$29$
d
The correct formula of diammine dichlorodicyano chromate $(III)$ is $\left[ CrCl _2( CN )_2\left( NH _3\right)_2\right]^{-}$. It contains two ammines, two cyano, and two chloro ligands. The oxidation state of chromium is $III$.Hence, the overall charge on the anion is $-1$.

A trinitro compound, $1, 3,5$ tris-($4$-nitrophenyl) benzene, on complete reaction with an excess of $\mathrm{Sn} / \mathrm{HCl}$ gives major product, which on treatment with an excess of $NaNO_2 /  HCl$ at $0^{\circ} C$ provides $P$ as the product. $P$, upon treatment with excess of $H_2 O$ at room temperature, gives the product $Q$. Bromination of $Q$ in aqueous medium furnishes the product $R$. The compound $P$ upon treatment with an excess of phenol under basic conditions gives the product $S$.

The molar mass difference between compounds $Q$ and $R$ is $474 \mathrm{~mol}^{-1}$ and between compounds $P$ and $S$ is $172.5 \mathrm{~g} \mathrm{~mol}^{-1}$.

($1$)The number of heteroatoms present in one molecule of $R$ is. . . . .  .

[Use: Molar mass (in g mol ${ }^{-1}$ ): $\mathrm{H}=1, \mathrm{C}=12, \mathrm{~N}=14, \mathrm{O}=16, \mathrm{Br}=80, \mathrm{Cl}=35.5$

Atoms other than $\mathrm{C}$ and $\mathrm{H}$ are considered as heteroatoms]
