For example, the solid material Sc 3 C 4 (three parts scandium, four parts carbon) has ethane- and propanelike organic fragments (without their hydrogen atoms) that are embedded in a solid matrix of inorganic scandium ions. In another broadly diverse field called organometallic chemistry, chains...
When tetraethyl lead was added to a fuel, it was also necessary to add 1,2-dibromoethane (C2H4Br2) so that a vapor phase product, PbBr2, could leave the engine without leaving behind lead residues. As it turns out, the environmental effects of the exhaust gases of leaded gasoline ...
Recently, it has been found that well-dispersed nanoparticles (NPs), clusters, and isolated metal atoms (or single atoms, SAs) exhibited surprisingly different catalytic performances from bulk materials with the development of the advanced characterization tools and well-controlled synthesis technology, l...
To determine the total number of carbon atoms in the smallest optically active alkane, we need to identify the conditions that make an alkane optically active. An alkane is optically active if it has at least one chiral center, which is a carbon atom

How is the radius of a nucleus related to its mass number ? View Solution In three moles of ethane(C2H6), calculate the following: (i) Number of moles of carbon atoms. (ii) Number of moles of hydrogen atoms. (iii) Number of molecules of ethane. ...
Branch isomersare a kind of structural isomer found in organic molecules (i.e., those that contain carbon). Carbon can bind to other carbon atoms in addition to bonding to hydrogen atoms, so once a carbon "chain" bordered by a hydrogen atom chain grows long enough for the atoms to move...
The electrons are constrained in pairs to a region on a line between the centers of pairs of atoms. Van der Waals molecular. A material that has a very low melting point and that will not conduct electricity either as a solid or when molten consists of molecules that are close-packed, ...
Covalent bonds are formed when atoms share their valence electrons with other atoms to acquire a full valence shell of electrons. They do so by overlapping their atomic or hybrid orbitals. The type of overlap depends on the type of bond that the atoms form....
