condensed structural formulas → kondenzirane strukturne formule

Condensed structural formulas are shortened and easier layout of structural formulas of organic compounds (butane, CH₃(CH₂)₂CH₃).

congener → srodnost

Congener is a term in chemistry that refers to one of many variants or configurations of a common chemical structure. Elements belonging to the same group on the periodic table. For example, sodium and potassium are congeners.

conjugated double bond → konjugirana dvostruka veza

Conjugated double bond in organic compounds is a system of double bonds between atoms which are separated by one single bond (1,3-butene, H₂C=CH-CH=CH₂).

cumulated double bond → kumulirana dvostruka veza

Cumulated double bond in organic compounds is a system of two double bonds on the same atom of carbon (C=C=C)

cyanogen → cijan

Cyanogen is a colourless gas, (CN)₂ with a pungent odour. The compound is very toxic. It my be prepared in the laboratory by heating mercury (II) cyanide.

decomposing → raščinjavanje

Decomposing in analytical chemistry means that a certain substance is converted, by melting it with a suitable melting medium (sodium carbonate, sodium hydroxide, sodium peroxide, ...) in the kind of compound which will afterwards that dissolve in water, acid or base very easily.

dehydrogenation → dehidrogenacija

Dehydrogenation is a chemical reaction in which hydrogen is removed from a compound. Dehydrogenation of organic compounds converts single carbon-carbon bonds into double bonds. It is usually affected by means of a metal catalyst or in biological systems by enzyme dehydrogenases.

derivative → derivat

Derivative is a compound that is derived from some other compound and usually maintains its general structure, e.g. trichlormethane (chloroform) is a derivative of methane.

chiral molecule → kiralne molekule

Chiral molecule is a molecule which cannot be superimposed on its mirror image. A common example is an organic molecule containing a carbon atom to which four different atoms or groups are attached. Such molecules exhibit optical activity, i.e., they rotate the plane of a polarised light beam.

chlorophyll → klorofil

Chlorophyll is a green pigment present in green plants and cyanobacteria. Chlorophyll is essential in the transformation of light energy to chemical energy in photosynthesis. Chlorophyll absorbs light mostly in the blue and red ends of the visible spectrum, and very little in the green wavelengths. That green light is reflected, giving us the leaf colour we see.
