| Description | This compound belongs to the class of organic compounds known as siloxanes. These are saturated silicon-oxygen hydrides with unbranched or branched chains of alternating silicon and oxygen atoms (each silicon atom is separated from its nearest silicon neighbours by single oxygen atoms). The general structure of unbranched siloxanes is H3Si[OSiH2]nOSiH3. H3Si[OSiH2]nOSiH[OSiH2OSiH3]2 is an example of a branched siloxane. By extension hydrocarbyl derivatives are commonly included. |
