According to some authors, organyl derivatives of acidic hydrogen of other acids are esters as well (e.g. amides), but not according to the IUPAC. [ 1 ] An example of an ester formation is the substitution reaction between a carboxylic acid ( R−C(=O)−OH ) and an alcohol (R'OH), forming an ester ( R−C(=O)−O−R' ), where R and R′ are ...
An ester of a carboxylic acid.R stands for any group (typically hydrogen or organyl) and R ′ stands for any organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (R ′).

is an alkaline solution of potassium permanganate; used in organic chemistry as a qualitative test for the presence of unsaturation, such as double bonds; N-Bromosuccinimide: used in radical substitution and electrophilic addition reactions in organic chemistry. Also acts as a mild oxidizer to oxidize benzylic or allylic alcohols.
Acetoacetic esters are used for the acetoacetylation reaction, which is widely used in the production of arylide yellows and diarylide dyes. [3] Although the esters can be used in this reaction, diketene also reacts with alcohols and amines to the corresponding acetoacetic acid derivatives in a process called acetoacetylation.
For esters such as ethyl acetate (CH 3 COOCH 2 CH 3), ethyl formate (HCOOCH 2 CH 3) or dimethyl phthalate that are based on common acids, IUPAC recommends use of these established names, called retained names. The "-oate" changes to "-ate."
Phthalates (US: / ˈ θ æ l eɪ t s / UK: / ˈ θ ɑː l eɪ t s ˌ ˈ f θ æ l ɪ t s / [1] [2]), or phthalate esters, are esters of phthalic acid. They are mainly used as plasticizers , i.e., substances added to plastics to increase their flexibility, transparency, durability, and longevity.
In chemistry, acetylation is an organic esterification reaction with acetic acid. It introduces an acetyl group into a chemical compound. Such compounds are termed acetate esters or simply acetates. Deacetylation is the opposite reaction, the removal of an acetyl group from a chemical compound.
For organic compounds containing heteroatoms (other than C and H), the list of unsaturated groups is long but some common types are: carbonyl, e.g. ketones, aldehydes, esters, carboxylic acids (unsaturated) vs alcohol or ether (saturated) nitrile (unsaturated) vs amine (saturated) nitro (unsaturated) vs amine (saturated)
