Organic formulation. Cyclic Hydrocarbons.

Cyclic Hydrocarbons theory   Organic Formulation: Cyclic Hydrocarbons They are closed-chain hydrocarbons. Depending on whether or not they have unsaturations, they are classified as: Saturated monocyclic hydrocarbons (cycloalkanes). Unsaturated monocyclic hydrocarbons (cycloalkenes and cycloalkynes)   […]

Van der Waals Forces

Van der Waals Forces theory   Van der Waals forces, although they don’t form a chemical bond theirselves, they are responsible for the attraction between neutral and saturated molecules, which result in the condensed states […]

Covalent Bond theory

Covalent Bond   Covalent Bond (nonmetal-nonmetal):   There are many molecules whose formation can not be explained by the ionic bond, the simplest cases are molecules which are composed of identical atoms, such as H2, […]

Stoichiometry theory

Stoichiometry   Stoichiometry theory Lavoisier’s law of mass conservation: The total mass of the substances involved in chemical transformation remains constant and therefore the sum of the masses of the reactants must be equal to […]
