(B) $1$. The reaction of chlorobenzene with $NaOH$ at $623 \ K$ and $300 \ atm$ pressure gives sodium phenoxide.$2$. Sodium phenoxide,upon treatment with concentrated $H_2SO_4$ and concentrated $HNO_3$,undergoes nitration to form $2,4,6$-trinitrophenol,commonly known as picric acid.$3$. The molecular formula of picric acid is $C_6H_3N_3O_7$.$4$. The molar mass of $C_6H_3N_3O_7 = (6 	imes 12) + (3 	imes 1) + (3 	imes 14) + (7 	imes 16) = 72 + 3 + 42 + 112 = 229 \ g/mol$.$5$. The mass of hydrogen in one mole of picric acid is $3 	imes 1 = 3 \ g$.$6$. The weight percentage of hydrogen = $\frac{	ext{Mass of H}}{	ext{Molar mass of } Q} 	imes 100 = \frac{3}{229} 	imes 100 \approx 1.31\%$.

The weight percentage of hydrogen in $Q$,formed in the following reaction sequence,is. . . .
[Given : Atomic mass of $H = 1, C = 12, N = 14, O = 16, S = 32, Cl = 35$ ]
