Intro to Organic Chem Flashcards
Define functional group
A group of atoms which are responsible for the characteristic reactions of a compound
Define homologous series
A group of compounds with the same general formula
Define molecular formula
The actual number of atoms of each element in a compound
What is the displayed formula?
Showing all atoms and all covalent bonds (the proper diagram)
What is the structural formula?
Shows the arrangement of atom in word form (eg CH3CH2CH3)
Define empirical formula
The simplest whole number ratio of the atoms of each element in a compound
What is the skeletal formula?
The stick drawings
What is the general formula?
A type of empirical formula that represents the composition of any member of a homologous series
Define structural isomers
Compounds that have the same molecular but different structural formula
What is chain isomerism?
When there is more than one way of arranging the longest carbon chain
What are positional isomers?
Isomers with the same carbon chain and functional groups, but the functional groups are placed in a different place
What are functional group isomers?
Same molecular formulas but different functional groups
What are stereoisomers?
Molecules which have the same molecular and structural formula but in a different arrangement of atoms in 3D space
