A hydrocarbon ' P ' $\left(\mathrm{C}_4 \mathrm{H}_8\right)$ on reaction with HCl gives an optically active compound ' Q ' $\left(\mathrm{C}_4 \mathrm{H}_9 \mathrm{Cl}\right)$ which on reaction with one mole of ammonia gives compound ' $\mathrm{R}^{\prime}\left(\mathrm{C}_4 \mathrm{H}_{11} \mathrm{~N}\right)$. ' $\mathrm{R}^{\prime}$ on diazotization followed by hydrolysis gives ' S '. Identify $\mathrm{P}, \mathrm{Q}, \mathrm{R}$ and S .

$\mathrm{A} \xrightarrow[\text { (i) } \mathrm{H}_3 \mathrm{O}^{+}]{\text {(i) } \mathrm{NaH}} \mathrm{B} \xrightarrow[\text { (ii) } \mathrm{H}_2 \mathrm{SO}_4, \Delta]{\text { (i) } \mathrm{EOH}} \mathrm{C}$

' A ' shows positive Lassaign's test for N and its molar mass is 121 .

' B ' gives effervescence with aq $\mathrm{NaHCO}_3$.

'C' gives fruity smell.

Identify $\mathrm{A}, \mathrm{B}$ and C from the following.

Match List - I with List - II.

List - I (Conversion)	List - II (Reagents, Conditions used)
	(I) Warm H2O
	(II) (a) NaOH, 368K; (b) H3O+
	(III) (a) NaOH, 443K; (b) H3O+
	(IV) (a) NaOH, 623K, 300 atm; (b) H3O+
