Show Answer

Answer:

Correct Answer: B

Solution:

% of chlorine $ =\frac{Massofchlorine}{Massoforganiccompound}\times 100 $

Chloral $ (CCl_3CHO)=\frac{106.5}{147.5}\times 100=72.20 $

Pyrene $ (CCl_4)=\frac{142}{154}\times 100=92.20 $

Highest Gammexene $ (C_6H_6Cl_6)=\frac{213}{291}\times 100=73.19 $
