two different structures are possible: a linear structure designatedn-butane and a branched structure called iso-butane. These two structures have the same molecular formula, C4H10, but a different order of attachment of theirconstituentatoms. The two molecules are termed structural isomers. Each of...

Still, our finding turns it into an important tool to increase molecular mass or as a C2-spacer to optimize the spatial arrangement of functional groups. All compound classes exhibit a noticeable increase in two-carbon mass, known as C2-chemistry. This phenomenon closely resembles the C2-...
Chloroform is an organic compound with formula CHCl3. It is one of the four chloromethanes.The colorless, sweet-smelling, dense liquid is a trihalomethane, and is considered hazardous. Several million tons are produced annually as a precursor to PTFE and refrigerants, but its use for refrigeran...
