After they are activated by trifluoroacetic acid, these compounds are the hydride source for ionic hydrogenation. Bifunctional coupling agents named for having these organic compounds as head groups are used to adhere polymers to inorganic surfaces. These compounds form adducts with active hydrogens to derivatize polar analytes before gas chromatography. In a process named for these compounds, they self-assemble on surface-exposed oxygens to form a monolayer that end-caps chromatography columns and renders glass chemically inert. Chlorinated and branched examples of these compounds, such as TBSCl (“T-B-S-C-L”), form ethers in the most common method to protect alcohols. One of these compounds bearing four methyl groups is assigned a chemical shift of 0 ppm in NMR. For 10 points, name these hydro·carbons that contain an atom of the element below carbon on the periodic table. ■END■
ANSWER: silanes [or organosilanes; or organosilicon compounds; or silyl groups; accept hydrosilanes; accept chlorosilanes; reject “silanols,” “silyl ethers,” “siloxanes,” “silicon,” or “Si”]
