A borane is an inorganic chemical compound of boron and hydrogen. Boranes are often unstable. They are named by analogy with the alkanes, which are carbon-hydrogen compounds.

German chemist Alfred Stock was the first scientist to characterize the series of boron-hydrogen compounds by analogy with hydrocarbons.

There are 2 major classes of boranes:

  • nidoboranes (general formula BnHn+4)
  • arachnoboranes (general formula BnHn+6)

For example: The salts of boranes are called borohydrides.
