Organc chemistry Flashcards
Homologous series
Homologous series have the same general formula with the neighbouring members of the series differing by –CH2-. They have similar chemical properties and they show a gradual change in physical properties.
Empirical formula
The empirical formula shows the simplest whole number ration of atoms of each element in a particle of the substance.
Molecular formula
The molecular formula shows the actual number of atoms of each element in a molecule of the substance.
Display formula
The structural formula shows the arrangement of atoms and bonds within a molecule.
Saturated organic compound
A saturated organic compound contains only carbon to carbon single bonds.
General formula
The general formula shows the proportion of atoms in a member of a homologous series.
Isomers
Isomers have the same molecular formula but their atoms are arranged differently.
