A Correct answer
Explanation

Chloroform (trichloromethane) has the chemical formula CHCl3, containing one carbon atom, one hydrogen atom, and three chlorine atoms. It was widely used as an anesthetic in the 19th century before its toxicity was fully understood. CH2O is formaldehyde, CH2Cl2 is dichloromethane, and COCl is not a stable molecular formula (phosgene is COCl2).
