Silane (or Silicane) is an inorganic compound with chemical formula, SiH4. It is a colourless, pyrophoric, toxic gas with a sharp, repulsive smell, somewhat similar to that of acetic acid. Silane is of practical interest as a precursor to elemental silicon. Silane with alkyl groups are effective water repellents for mineral … See more Commercial-scale routes Silane can be produced by several routes. Typically, it arises from the reaction of hydrogen chloride with magnesium silicide: It is also prepared from metallurgical-grade silicon in a … See more Silane is the silicon analogue of methane. Because of the greater electronegativity of hydrogen in comparison to silicon, this Si–H bond polarity is the opposite of that in the C–H bonds of methane. One consequence of this reversed polarity is the greater … See more • Binary silicon-hydrogen compounds (sometimes called silanes) • Silanization • Magnesium silicide • Methane, in which Carbon (in that compound) and Silicon (in this compound) are together in the Carbon group.
