Dibromomethane or methylene bromide, or methylene dibromide is a halomethane. It is slightly soluble in water but very soluble in carbon tetrachloride, diethyl ether and methanol.
Its refractive index is 1.5419 (20 °C, D).
==Preparation==
Dibromomethane can be prepared from bromoform by reaction
:CHBr3 + Na3AsO3 + NaOH → CH2Br2 + Na3AsO4 + NaBr
using sodium arsenite and sodium hydroxide.〔(Methylene bromide preparation )〕
Another way is to prepare it from diiodomethane and bromine.
