Organic chemistry is a science about all compounds which consist of carbon atoms, except carbonates and oxides of carbon.
Computational chemistry is a branch of chemistry concerned with the prediction or simulation of chemical properties, structures, or processes using numerical techniques.
Electroanalytical chemistry chemistry is the application of electrochemical cells and electrochemical techniques for chemical analysis. The analyte is dissolved in the electrolyte of the cell, and one can perform either qualitative analysis (determination of the type of constituents present) or quantitative analysis (determination of the amount of a given constituent).
Inorganic chemistry, the branch of chemistry concerned with compounds of elements other than carbon. Certain simple carbon compounds, such as CO, CO2, CS2, carbonates CO32- and cyanides CN-, are usually treated in inorganic chemistry.
1. Organic refers to any chemical compound based on carbon (C) with the exception of some of the simple compounds of carbon, such as carbon dioxide, which are frequently classified as inorganic compounds. Additional elements that are commonly found in organic compounds are hydrogen (H), nitrogen (N), oxygen (O), phosphorus (P) and sulfur (S).
2. Organic or organically-grown foods are grown or raised without synthetic fertilizers, pesticides, growth stimulators, or antibiotics and other drugs. Pests are controlled by cultivation techniques and the use of pesticides derived from natural sources and the use of natural fertilizers. In addition, organically grown foods must also be stored without the use of chemicals such as artificial additives and preservatives, and without food irradiation.
Organic acid is an organic compound which is sour, most often these are carboxylic acids (RCOOH).
Organic solvent is an organic liquid in which organic (non-polar) substances melt.
Quantum chemistry is a theoretical branch of chemistry that concerns the application of quantum mechanics to chemical problems.
Acetals are organic compounds having the structure R2C(OR’)2 (R’ ≠ H). They are organic compounds formed by addition of alcohol molecules to aldehyde or ketone molecules. Originally, the term was confined to derivatives of aldehydes (one R = H), but it now applies equally to derivatives of ketones (neither R = H ). Mixed acetals have different R’ groups. The formation of acetals is reversible; acetals can be hydrolysed back to aldehydes (ketone) in acidic solutions.
Acetal, 1,1-diethoxyethane (CH3CH(OC2H5)2), is an organic compound, pleasant smelling, formed by addition of ethyl alcohol to ethanal (acetaldehyde). It is used as a solvent and in synthetic organic chemistry.
Biochemistry is the study of the chemistry of living organisms, especially the structure and function of their chemical components (principally proteins, carbohydrates, lipids and nucleic acids).
