dichloromethane

As nouns the difference between dichloromethane and chloroform

is that dichloromethane is the partially halogenated hydrocarbon CH₂Cl₂ widely used as a solvent while chloroform is a halogenated hydrocarbon, trichloromethane, CHCl₃; it is a volatile, sweet-smelling liquid, used extensively as a solvent and formerly as an anesthetic.

As a verb chloroform is

to treat with chloroform, or to render unconscious with chloroform.

As nouns the difference between dichloroethene and dichloromethane

is that dichloroethene is any of several isomeric organochlorides with the molecular formula C₂H₂Cl₂ while dichloromethane is the partially halogenated hydrocarbon CH₂Cl₂ widely used as a solvent.

As nouns the difference between dichloromethane and dichloroethane

is that dichloromethane is the partially halogenated hydrocarbon CH₂Cl₂ widely used as a solvent while dichloroethane is either of two isomeric organochlorides with the molecular formula C₂H₄Cl₂: 1,1-dichloroethane (ethylidene dichloride) and 1,2-dichloroethane (ethylene dichloride).

As nouns the difference between dichloromethane and dichloromethyl

is that dichloromethane is the partially halogenated hydrocarbon CH₂Cl₂ widely used as a solvent while dichloromethyl is the univalent radical CHCl₂- derived from dichloromethane.
