June 10, 2019. 126oC), a brown liquid, is very toxic by inhalation, causes severe burns, reacts violently with water, hot alkali or alkaline earth (not Mg) metals One thing to keep in mind while drawing Lewis structure is that the Octet Rule can be violated in these three situations; but, we don’t need to think about it each time as it is rare and these exceptions will only occur when necessary. Boron trifluoride is a colorless gas which is formed by several reactions where a boron compound comes in contact with a fluorinating agent. An excess of the etherate in ether should be distilled in an all‐glass apparatus with calcium hydroxide to remove volatile acids and to reduce bumping.
