Physical Properties
Colorless liquid; density 0.79 g/mL at 0°C; freezes at –108°C; boils at 84.3°C; vapor density 5.48 g/L at STP; decomposes in water.
Description
Silicon forms a series of hydrides known as silanes, formula SinH2n+2, where n is the number of silicon atoms in the molecule. This general formula for the silicon hydrides is similar to the CnH2n+2 for the alkane class of hydrocarbons.
Chemical Properties
colorless liquid; enthalpy of vaporization 35.56 kJ/mol; vapor pressure at 0°C 9.1mm Hg; critical temp 249°C [CIC73] [CRC10]
