Organic Molecules Flashcards
Molecular formula
A chemical formula that indicates the element and numbers
of each of the atoms in a molecule.
Structural formula
A structural formula of a compound shows which atoms are
attached to which within the molecule. Atoms are represented by their chemical
symbols and lines are used to represent ALL the bonds that hold the atoms
together.
Condensed structural formula
This notation shows the way in which atoms are
bonded together in the molecule
CH3CH2COCH3
Condensed structural formula
This notation shows the way in which atoms are
bonded together in the molecule
CH3CH2COCH3
Hydrocarbon
Organic compounds that consist of hydrogen and carbon only.
Homologous series
A series of organic compounds that can be described by
the same general formula OR in which one member differs from the next with a
CH2 group
Saturated compounds
Compounds in which there are no multiple bonds
between C atoms in their hydrocarbon chains
Unsaturated compounds
Compounds with one or more multiple bonds between
C atoms in their hydrocarbon chains
Functional group
A bond or an atom or a group of atoms that determine(s) the
physical and chemical properties of a group of organic compounds
Functional group
A bond or an atom or a group of atoms that determine(s) the
physical and chemical properties of a group of organic compounds
Structural isomer
Organic molecules with the same molecular formula, but
different structural formulae
Chain isomers
Same molecular formula, but different types of chains
Positional isomers
Same molecular formula, but different positions of the side
chain, substituents, or functional groups on the parent chain
Functional isomers
Same molecular formula, but different functional groups
