Pyrene $(CCl_4)$

Vedclass · Answer

(A) To determine the highest chlorine content,we calculate the percentage of chlorine in each compound:$1$. Pyrene $(CCl_4)$: Molar mass = $12 + 4 	imes 35.5 = 154 \ g/mol$. Chlorine mass = $4 	imes 35.5 = 142 \ g$. Percentage = $(142/154) 	imes 100 \approx 92.2\%$.$2$. $DDT$ $(C_{14}H_9Cl_5)$: Molar mass = $14 	imes 12 + 9 	imes 1 + 5 	imes 35.5 = 168 + 9 + 177.5 = 354.5 \ g/mol$. Chlorine mass = $5 	imes 35.5 = 177.5 \ g$. Percentage = $(177.5/354.5) 	imes 100 \approx 50.1\%$.$3$. Chloral $(CCl_3CHO)$: Molar mass = $12 + 35.5 	imes 3 + 12 + 1 + 16 + 1 = 147.5 \ g/mol$. Chlorine mass = $3 	imes 35.5 = 106.5 \ g$. Percentage = $(106.5/147.5) 	imes 100 \approx 72.2\%$.$4$. Gammaxene $(C_6H_6Cl_6)$: Molar mass = $6 	imes 12 + 6 	imes 1 + 6 	imes 35.5 = 72 + 6 + 213 = 291 \ g/mol$. Chlorine mass = $6 	imes 35.5 = 213 \ g$. Percentage = $(213/291) 	imes 100 \approx 73.2\%$.Comparing the percentages,Pyrene $(CCl_4)$ has the highest chlorine content.

Which of the following has the highest chlorine content by mass?
