organic chemistry Flashcards
what is the definition of an empirical formula?
simplest ratio of atoms in a chemical compound
what does the term nomenclature mean?
the systematic naming of organic molecules
who devised the nomenclature system?
the IUPAC
what does IUPAC mean?
The International Union of Pure and Applied Chemistry
what is the definition of an molecular formula?
an actual number of atoms of each element in a compound
what is the definition of an general formula?
a type of empirical formula which shows the composition of any compound
what is the definition of a structural formula?
- identifying the bonds between the atoms of the molecules.
(can be shown on how each molecule are grouped)
what is an example of a general formula?
CₙH₂ₙ+ₙ (alkane)
what is an example of a structural formula?
CH₃ CH₂ CH₂ CH₃ - propane
what is the definition of a displayed formula?
showing all the bonds between the atoms of the molecule
what is the definition of a skeletal formula?
a representation of an molecular structure where the covalent bonds are shown as lines.
what is the definition of an homologous series?
family of compounds with same functional group and follow a general formula
what is the definition of an functional group?
a group of atoms/ an atom that give a compound it’s specific properties
what are isomers?
isomers come in pairs and have the same molecular formula but have a different arrangement so therefore have different properties
- however behave the same chemically
