Question

Silicon hydrides are called:

• A. silicones
• B. silicates
• C. silicides
• D. silanes

Answer 1

Answer: (D)

Silicones are organo-silicon polymers that have $R_{2}SiO$ as a repeating unit whereas silicates are compounds having the repeating unit as $Si{O}_4^{4-}$.

A silicide is a compound that has silicon with (usually) more electropositive elements.

Silanes are silicon-hydrogen compounds.
