The side chains are: an ethyl- at carbon 4, an ethyl- at carbon 8, and a butyl- at carbon 12. Note: the −O−CH 3 at carbon atom 15 is not a side chain, but it is a methoxy functional group. There are two ethyl- groups. They are combined to create, 4,8-diethyl. The side chains are grouped like this: 12-butyl-4,8-diethyl.
Arene substitution patterns are part of organic chemistry IUPAC nomenclature and pinpoint the position of substituents other than hydrogen in relation to each other on an aromatic hydrocarbon. Ortho , meta , and para substitution
The numbers 200-900 would be confused easily with 22 to 29 if they were used in chemistry. khīlioi = 1000, diskhīlioi = 2000, triskhīlioi = 3000, etc. 13 to 19 are formed by starting with the Greek word for the number of ones, followed by και (the Greek word for 'and'), followed by δέκα (the Greek word for 'ten').

In organic chemistry, a cyanohydrin reaction is an organic reaction in which an aldehyde (−CH=O) or ketone (>C=O) reacts with a cyanide anion (N≡C ...
N-Hydroxysuccinimide (NHS) is an organic compound with the formula (CH 2 CO) 2 NOH. It is a white solid that is used as a reagent for preparing active esters in peptide synthesis. It can be synthesized by heating succinic anhydride with hydroxylamine or hydroxylamine hydrochloride .
The manganate(VI) ion is a d 1 ion and is tetrahedral with bond angles of approximately 109.5°. The Mn−O bond lengths in BaMnO 4 and K 2 MnO 4 are identical at 1.66 Å. In comparison, the Mn-O bond length in MnO 2− 4 is longer than in MnO 4 − of 1.56 Å and shorter than the Mn−O bond found in MnO 2, 1.89 Å.
The following outline is provided as an overview of and topical guide to organic chemistry: . Organic chemistry is the scientific study of the structure, properties, composition, reactions, and preparation (by synthesis or by other means) of carbon-based compounds, hydrocarbons, and their derivatives.
