Element: only 1 type of atom; this definition is applied to things both bonded and not to itself. I don't know whether these terms apply microscopically, macroscopically, or both. For example, I think 1 $\ce{H2O}$ molecule is a compound but is a bathtub of them called a mixture (as it contains more than 1 atom type), a compound, or both?
According to the definition of organic compounds on Wikipedia: An organic compound is any member of a large class of gaseous, liquid, or solid chemical compounds whose molecules contain carbon. Carbonates, simple oxides of carbon, and cyanide molecules do have carbon, but they are not regarded as organic. The same Wikipedia article on organic ...
The correct definition of chirality is given in the IUPAC gold book as follows: chirality The geometric property of a rigid object (or spatial arrangement of points or atoms) of being non-superposable on its mirror image; such an object has no symmetry elements of the second kind (a mirror plane, σ = S 1, a centre of inversion, i = S 2, a rotation-reflection axis, S 2n).
According to metamerism in polyvalent functional groups, if both alkyl groups' around functional group are different then they are considered as metamers but in few books it is given that if one of the alkyl group is different then it is a metamer. In my opinion, for e.g. diethyl ether and methyl propyl ether are metamers.
This also describes another common use of per-, perhalogenated compounds. In that context, it usually means that all hydrogens present in the parent compound, that were bonded to a carbon, have been replaced with a halogen, for example perfluoroethylene (C2F4, also known as tetrafluoroethylene, the monomer of Teflon(PTFE))
In chemistry, the chemical property of having the same proportion of atomic components in different arrangements (obsolete, replaced with isomer). In organic chemistry, compounds having the same molecular formula but different number of carbon atoms (alkyl groups) on either side of functional group ( i.e., -O-,-S-, -NH-, -C(=O)-) are called ...
That said, the high-school definition is too simplistic. It is common for compounds to be an acid, a base and a salt all at the same time; consider for example sodium bicarbonate ($\ce{Na+HCO3-}$). It is made of cations and anions, and therefore is definitely a salt.
This common center of mass is called the barycenter. Barycenters also help astronomers search for planets beyond our solar system! In Crystal Field Theory (CFT), electrons in the d d -orbitals are repelled to different degrees by the ligands. The degeneracy of the d d -orbitals is lifted. The Barycenter is the average energy of the d d ...
answered. 28 49. There is an easy way of identifying optical isomers in coordination compounds. Roughly draw the structures of all possible isomers of the compound by interchanging the ligand positions. Cross out those structures whose mirror image overlaps with itself. The remaining are optical isomers of the given compound.
It means that water can be bound only with intermolecular interactions, but it exists in the structure in a stoichiometric ratio. Source. Also, according to this article. As a result, for example in direct addition reactions, where there is ignorance about the structural relation of the compounds, we use a dot. ⋅5.
