Molecular Orbital Theory
The Lewis structures, the VSEPR theory and the valence binding method form a powerful combination to describe covalent bonding and molecular structures. The results are satisfactory for most of our purposes. However, sometimes, chemists need […]
Pure substances and mixtures
Matter is made up of tiny units called atoms. We currently know that there are 119 different types of atoms, which are the basis of the 119 elements of the periodic table (including “unnunennio” which […]
The chemistry of carbon
Since its beginnings in the 18th and 19th centuries, chemistry has been divided into two main branches: organic chemistry and inorganic chemistry. Organic Chemistry: It was associated with the chemistry of living beings and the […]
Changes of states of matter
Matter is everything that surrounds us that has mass and weight, that occupies a place in the space, that is perceptible by one of our senses and that is opposed to changing position, which is, […]
Empirical and molecular formula
The empirical formula is the simplest expression to represent a chemical compound. It tells us the elements that are present and the minimum proportion in whole numbers between their atoms. This formula is also known […]
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) […]
Organic formulation. Alkynes.
Organic Formulation Theory: Alkynes Hydrocarbons with triple bonds, Acetylenes or Alkynes They are hydrocarbons having one or more triple bonds between carbon atoms. The general formula for compounds with a triple single bond, is […]
Organic formulation. Alkenes
Organic Formulation Theory: Alkenes Hydrocarbons with double bonds, Olefins or Alkenes. They are hydrocarbons having one or more double bonds between the carbon atoms. The general formula with a single double bond is CnH2n. […]
Organic formulation. Alkanes.
Organic Formulation Theory: Alkanes Saturated hydrocarbons, paraffins or Alkanes They are called saturated hydrocarbons or alkanes all compounds made of carbon and hydrogen, which are of open-chain and have single bonds. Straight-chain alkanes. […]
Chemical Kinetics theory
Chemical Kinetics Chemical Kinetics studies the speed of chemical processes and determines the factors which influence on it. It aims is to find mathematical expression that relates the speed of a chemical reaction with […]
