Alcohols

Alcohols are identified as having an -OH (hydroxyl) functional group attached to the parent chain. This (relatively) strong intermolecular force increases alcohol melting and boiling points. Because of the -OH atoms, alcohols are polar. However as the carbon chain (non-polar) increases in length, the overall polarity will become less polar. 

Alcohols can be made from haloalkanes and from oxidation of alkenes. Alcohols can undergo substitution, elimination, and oxidation reactions. For substitution reactions PCl₃ or SOCl₂ are sources of Cl, which replaces the -OH group. Elimination of alcohols to form alkenes is also a 'dehydration' reaction (concentrated H₂SO₄ reagent). ONLY primary alcohols oxidise to form carboxylic acids. Oxidants such as potassium permanganate (KMnO₄) and potassium dichromate (K₂Cr₂O₇) are reagents for this reaction. Potassium permanganate is purple and turns colourless when it reacts. Potassium dichromate is orange and turns green.

Chemical solution

Some of chemical solutions are very dangerous and toxic.

Types of Chemical Reactions

The vast number of chemical reactions can be classified in any number of ways. Under one scheme they can be categorized either as oxidation-reduction (electron transfer) reactions or non-oxidation-reduction reactions. Another completely different but common classification scheme recognizes four major reaction types: (1)  combination or synthesis reactions (2)  decomposition reactions (3)  substitution or single replacement reactions (4)  metathesis or double displacement reactions

What is Organic Chemistry

Organic chemistry is a chemistry sub-discipline involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. Study of structure includes many physical and chemical methods to determine the chemical composition and the chemical constitution of organic compounds and materials. Study of properties includes both physical properties and chemical properties, and uses similar methods as well as methods to evaluate chemical reactivity, with the aim to understand the behavior of the organic matter in its pure form (when possible), but also in solutions, mixtures, and fabricated forms. The study of organic reactions includes probing their scope through use in preparation of target compounds (e.g., natural products, drugs, polymers, etc.) by chemical synthesis, as well as the focused study of the reactivities of individual organic molecules, both in the laboratory and via theoretical (in silico) study.
