CHEMISTRY GLOSSARY
stereospecific reaction → stereospecifična reakcija
Stereospecific reactions are reactions that proceed predominantly to a single stereoisomeric product out. All metabolic conversions involving chiral molecules are stereospecific.
substitution → supstitucija
Substitution (substitution reaction) is a reaction in which an atom or fragment within a molecule is replaced with another atom or a fragment.
surface tension → površinska napetost
Surface tension (σ) is a property of liquids arising from unbalanced molecular cohesive forces at or near the surface, as a result of which the surface tends to contract and has properties resembling those of a stretched elastic membrane. As a result of which the surface tends to contract and has properties resembling those of a stretched elastic membrane.
temperature → temperatura
Temperature is a measure to the average kinetic energy of its molecules. The SI unit in which thermodynamic temperature is expressed is the kelvin (K).
gasoline → motorni benzin
Gasoline is a complex mixture of volatile hydrocarbons that may have between 5 to 12 carbons. The major components are branched-chain paraffins, cycloparaffins, and aromatics. Gasoline is most often produced by the fractional distillation of crude oil as the fraction of hydrocarbons in petroleum boiling between 30 °C and 200 °C. The quality of a fuel is measured with its octane number. Octane number is the measure of the resistance of gasoline against detonation or preignition of the fuel in the engine. The higher the octane number, the more compression the fuel can withstand before detonating. The octane number is determined by comparing the characteristics of a gasoline to isooctane with good knocking properties (octane number of 100) and heptane with bad (octane number of 0).
terminal → terminalni
Terminal in chemistry means: the end of a polymer molecule and a point at which electron connections can easily be made or broken.
unsaturated hydrocarbon → nezasićeni ugljikovodik
Unsaturated hydrocarbons are organic compounds containing double (alkenes) or triple (alkynes) bonds in their molecules.
valence bond theory → teorija valentne veze
Valence bond theory is a theory that explains the shapes of molecules in terms of overlaps between half-filled atomic orbitals, or half filled hybridised orbitals.
van der Waals’ force → van der Waalsova sila
Van derWaals’ force is the weak attractive force between two molecules which arises from electric dipole interactions. It can lead to the formation of stable but weakly bound dimer molecules or clusters. They are named after the Dutch physicist Johannes van der Waals (1837-1923).
