(B) The percentage of chlorine is calculated as: $	ext{Percentage of } Cl = \frac{	ext{Mass of } Cl}{	ext{Molar mass of compound}} 	imes 100$. $1$. Chloral $(CCl_3CHO)$: $\frac{106.5}{147.5} 	imes 100 \approx 72.20\%$. $2$. Pyrene $(CCl_4)$: $\frac{142}{154} 	imes 100 \approx 92.20\%$. $3$. $PVC$ $(C_2H_3Cl)_n$: $\frac{35.5}{62.5} 	imes 100 \approx 56.8\%$. $4$. Gammexane $(C_6H_6Cl_6)$: $\frac{213}{291} 	imes 100 \approx 73.19\%$. Comparing these values,Pyrene $(CCl_4)$ has the highest percentage of chlorine.
