Definition Molecules are defined chemical compounds in which at least two, but usually more, atoms are covalently bonded together. Typical atoms in molecules are nonmetals such as carbon (C), hydrogen (H), oxygen (O), nitrogen (N), sulfur (S), phosphorus (P), and halogens (fluorine (F), chlorine (Cl), bromine (I), iodine (I)). Organic compounds contain carbon atoms. The … Molecules

Definition Ethers are organic molecules with the general structure R1-O-R2, where R1 and R2 are identical for symmetrical ethers. The radicals can be aliphatic or aromatic. Cyclic ethers exist, such as tetrahydrofuran (THF). Ethers can be prepared using, for example, Williamson’s synthesis: R1-X + R2-O–Na+ R1-O-R2 + NaX X stands for halogens Nomenclature Trivial names … Ether
Definition and properties Melting point is a characteristic temperature at which a substance changes from solid to liquid state. At this temperature, the solid and liquid occur in equilibrium. A typical example is ice, which melts at 0 °C and becomes liquid water. The melting point is slightly dependent on atmospheric pressure, which is why … Melting Point
Definition We know from everyday life that the same volumes of different substances do not have the same mass. A liter measure full of down is much lighter than a liter measure filled with sugar. Fresh snow is lighter than ice, and ice is slightly lighter than water, although they are all H2O. Density is … Density
