Types of Formulae Flashcards
Hydrocarbons are compounds that are made up of
hydrogen and carbon only
The general formula is a formula that represents a
homologous series of compounds using letters and numbers
Eg. the general formula of alkanes is CnH2n+2
A homologous series is a
group of organic compounds that have the same functional group, the same general formula and the same chemical properties
The structural formula is a formula that shows
how the atoms are bonded to each carbon atom in a molecule
The displayed formula is a
2D representation of an organic molecule showing all its atoms (by their symbols) and their bonds (by single, double or triple bonds)
The skeletal formula is a
simplified displayed formula with all the carbon and hydrogen (C-H) bonds removed
