11) Basic concepts of organic chemistry Flashcards
Define hydrocarbon
a compound containing carbon and hydrogen only
Define saturated
single bonds only
Define unsaturated
contains carbon-to-carbon multiple bonds
Define homologous series
a family of compounds with similar chemical properties whose successive members differ by the addition of a -CH2- group
Define alkanes
the simplest hydrocarbon homologous series with single carbon-to-carbon bonds and the general formula CnH2n+2
What are the bond angles around a carbon atom in an alkane?
109.5 degrees
Define functional group
the part of the organic molecule that is largely responsible for the molecule’s chemical properties
Define aliphatic
carbon atoms joined to each other in unbranched (straight) or branched chains, or non-aromatic rings
Define alicyclic
carbon atoms joined to each other in ring (cyclic) structures, with or without branches
Define aromatic
some or all carbon atoms are found in a benzene ring
