amide → amid

Amide is an organic compound that contains a carbonyl group bound to nitrogen. The simplest amides are formamide (HCONH₂) and acetamide (CH₃CONH₂).

Amines are compounds formally derived from ammonia by replacing one, two, or three hydrogen atoms by hydrocarbyl groups, and having the general structures RNH₂ (primary amines), R₂NH (secondary amines), R₃N (tertiary amines). Examples are methylamine, CH₃NH₂; dimethylamine, CH₃NHCH₃; and trimethylamine, (CH₃)₃N.

amino acids → aminokiseline

Amino acids are compounds containing both a carboxylic acid group (-COOH) and an amino group (-NH₂ ). The most important are the α-amino acids, in which the -NH₂ group in attached to the C atom adjacent to the -COOH group. In the β-amino acids, there is an intervening carbon atom.

ammonia → amonijak

Ammonia is a colourless gas, NH₃, with a strong pungent odour. It is easily soluble in water and alcohol. Liquid ammonia has some similarity to water as it is hydrogen bonded and has a moderate dielectric constant, which permits it to act as an ionising solvent.

aqueous solution → vodena otopina

Aqueous solutions are those solutions where water is the solvent. An aqueous solution found in an equation describing a chemical reaction is denoted by the state symbol, (aq).

ash → pepeo

Ash is an inorganic part of some matter or mixture which remains after the organic part has burnt up.

auxochrome → auksokromna grupa

Auxochrome is a group or substructure in a molecule that influences the intensity of absorption of the molecule.

azo compounds → azo-spojevi

Azo compounds are organic compounds containing the group -N=N- linking two other groups. They can be formed by reaction of a diazonium ion with a benzene ring.

bitumen → bitumen

Bitumen is the final residue from petroleum fractional distillation, black tar containing free carbon.

boiling point elevation → povišenje vrelišta

Boiling point elevation is an elevation of the boiling point of a solvent is observed when substances are dissolved in it. The amount by which the boiling point is elevated is proportional to the number of molecules of solute and independent of their nature.
