The chloroform molecule can be viewed as a methane molecule with three hydrogen atoms replaced with three chlorine atoms, leaving a single hydrogen atom. The name "chloroform" is a portmanteau of terchloride (tertiary chloride, a trichloride) and formyle, an obsolete name for the methylylidene radical (CH) derived from formic acid. [citation ...

In 1835, the French chemist Auguste Laurent recognised chloroform as CCl 2 • HCl (then written as C 8 Cl 8 • H 4 Cl 4) [a] in his paper on analysing some organohalides. Laurent also predicted a compound seemingly consisting of 2 parts dichlorocarbene which he named Chlorétherose (possibly Tetrachloroethylene, which was not known to exist at the time.) [8]
Alizarin is one of ten dihydroxyanthraquinone isomers. It is soluble in hexane and chloroform, and can be obtained from the latter as red-purple crystals, melting point 277–278 °C. [3] Alizarin changes color depending on the pH of the solution it is in, thereby making it a pH indicator. [17]
When the alkyl radical is fully formed in the transition state, it can benefit fully from any resonance stabilization present thereby maximizing selectivity. [dubious – discuss] [citation needed] Bond dissociation energies strongly influence any radical process and in a few unusual cases, free-radical halogenation can regioselect.

The organic compound 1,1,1-trichloroethane, also known as methyl chloroform and chlorothene, is a chloroalkane with the chemical formula CH 3 CCl 3. It is an isomer of 1,1,2-trichloroethane . A colourless and sweet-smelling liquid, it was once produced industrially in large quantities for use as a solvent . [ 5 ]
