What does boron trichloride smell like?
Boron trifluoride is a colorless gas with an odor described both as pungent and suffocating and as pleasant. Although the gas is stable in dry air, it immediately forms a dense white mist or cloud when exposed to moist air.
What type of bond is boron tribromide?
Its molar mass is 250.522 g mol-1. Boron atom is in the molecule center and forms three simple bonds with each bromine. BBr3 molecule is an exception to the rules of octet of valence electrons. Boron tribromide has a planar-trigonal structure, thus, there is 120º between each bonds.
Is boron an explosive?
* Boron Trichloride is a REACTIVE CHEMICAL and an EXPLOSION HAZARD.
How is boron tribromide used as a reagent?
Boron tribromide (BBr3) is a strong Lewis acid generally used as a reagent for the deprotection of ethers. Alkyl aryl ethers are cleaved at the alkyl-oxygen bond to give ArOH and alkyl bromides. In a particular case, BBr3 was used to cleave acetals that could not be deprotected under standard acidic conditions.
