A. Diborane is a colorless, toxic, and pyrophoric gas with a sweet odor:
Chemical formula: B₂H₆
Molar mass: 27.67 g/mol
Boiling point -92 °C
Melting point -165.5 °C

B. Diborane is used in many applications, including:
Electronics: Imparts electrical properties in pure crystals
Rocket propellants: Used in rocket fuels
Rubber vulcanizer: Used in the polymerization process for rubber hoses, shoe soles, toys, and more
Reducing agent: Used in many chemical reactions to reduce reactants
Catalyst: Used as a catalyst for hydrocarbon polymerization

C. Diborane is explosive and irritating, so it must be handled with care


D. Borane is a synthetic boron hydride that is part of the boron family, which is group 13 of the periodic table:
Borane
A class of inorganic boron-hydrogen compounds with the formula BxHy. The simplest borane is BH3, which consists of a single boron atom and three hydrogens.
Boron family
Includes boron (B), aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). The elements in this group have three electrons in their outer shell.
Multicenter bonding
Borane molecules were previously called "electron-deficient" because of their multicenter bonding, but this is incorrect.
Hydrides
The elements in group 13 do not combine directly with hydrogen to form hydrides, but some hydrides have been prepared indirectly.
Covalent bonding
Boron is mainly a covalent bonding element, while the other elements in group 13 are predominantly ionic bonding elements
