Charge (q)   $=it=2*50*60=6000\mathrm{C}$

$\Rightarrow \mathrm{}6000C=\left(\frac{6000}{96500}F\right)$

${\mathrm{M}\mathrm{n}\mathrm{O}}_4^{-}+3{\mathrm{e}}^{(-)}+2{\mathrm{H}}_2\mathrm{O}\stackrel{\text{weakly alkaline medium}}{?}{\mathrm{M}\mathrm{n}\mathrm{O}}_2+4{\mathrm{O}\mathrm{H}}^{-}$

Mass of ${\mathrm{M}\mathrm{n}\mathrm{O}}_2$    deposited $=\frac{1}{3}*\frac{6000}{96500}*87=1.8$

$\to$ ${\pi }_{{\mathrm{K}\mathrm{N}\mathrm{O}}_3}={\pi }_{\text{glucose.}}$

$(\mathrm{i}\mathrm{C}\mathrm{R}\mathrm{T}{)}_{{\mathrm{K}\mathrm{N}\mathrm{O}}_3}=(\mathrm{C}\mathrm{R}\mathrm{T}{)}_{\text{glucose}}$

 $\frac{}{}\frac{}{}$ $\frac{\mathrm{i}*1.34}{101.1}*\mathrm{R}\mathrm{T}=\frac{4.77}{180}*\mathrm{R}*\mathrm{T}$

$\mathrm{i}=\frac{4.77}{180}*\frac{101.1}{1.34}=2$

Hence, extent of dissociation is $100\mathrm{\%}$

Kindly consider the following Image 

(1) Cimetidine $\mathrm{E}=\mathrm{P}\mathrm{h}-\mathrm{C}\mathrm{H}-{\mathrm{C}\mathrm{H}}_3$ ${}_{}$ Antacid

(2) Iproniazid ${\mathrm{C}\mathrm{H}}_3$ ${}_{}$ Antidepressant

(3) Penicillin $\to$ $$ Antibiotic

(4) Terfenadine $\to$ $$ Antihistamines

In ${\left. [\mathrm{F}\mathrm{e}?{\left({\mathrm{H}}_2\mathrm{O}\right)}_5\left(\mathrm{N}\mathrm{O}\right)\right]}^{2+}$

${\mathrm{F}\mathrm{e}}^{+1}\left(3{\mathrm{d}}^7\right)$

In ${\left. [{\mathrm{C}\mathrm{r}}^{+3}(\mathrm{C}\mathrm{N}{)}_6\right]}^{3-}$

${\mathrm{C}\mathrm{r}}^{+3}\left(3{\mathrm{d}}^3\right)$

 0.2 mole gives $\to 0.4$ $$ mole of $$ $\mathrm{A}\mathrm{g}\mathrm{C}\mathrm{l}$ (moles of $\mathrm{A}\mathrm{g}\mathrm{C}\mathrm{l}=\frac{57.45}{143}=0.4$ $\frac{}{}$ )

1 mole complex gives $\to \frac{0.4}{0.2}=2$ $\frac{}{}$ moles $\mathrm{A}\mathrm{g}\mathrm{C}\mathrm{l}$ $$

The correct answer should be $2^{\text{nd}}$ ${}^{}$ option.

As the difference in $3^{\text{rd}}$ ${}^{}$ and $4^{\text{th}}$ ${}^{}$ ionisation energy is high so atom contains 3 valence electrons. Hence, valency of the atom is 3 and the metal is trivalent. 4 mole of trivalent metal hydroxide will react with 6 mole of ${\mathrm{H}}_2{\mathrm{S}\mathrm{O}}_4$ ${}_{}{}_{}$, $\left(2\mathrm{M}(\mathrm{O}\mathrm{H}{)}_3+3{\mathrm{H}}_2{\mathrm{S}\mathrm{O}}_4?{\mathrm{M}}_2{\left({\mathrm{S}\mathrm{O}}_4\right)}_3+6{\mathrm{H}}_2\mathrm{O}\right)$

The rate of formation of $C$ $$ is three times the rate of decomposition of $$ $A$ .

The reactivity of ${\mathrm{S}}_{\mathrm{N}}1$ ${}_{}$ reaction depends upon stability of carbocation.
