Organic Classes Flashcards
homologous series
family of molecule with: same functional group similar chemical properties same general formula each sucessive member differs by addition of -CH2
organic class
molecules that have same functional group
functional group
site of reactivity in a molecule
can molecules have more than one functional group?
yes
alkane functional group
alkanyl
alkene functional group
alkenyl
alkyne functional group
alkynyl
alcohol functional group
hydroxyl
arene functional group
phenyl
trend in boiling points in homologous series (2)
boiling point increases as number of carbons increases
increased strength of london dispersion forces
boiling point decreases as number of branches increases
less surface area for london dispersion forces
alkanes
homologous series
hydrocarbon
general formula: CnH2n+2
saturated
alkenes
homologous series hydrocarbon general formula: CnH2n unsaturated contain one C-C double bond
alkynes
homologous series hydrocarbon unsaturated general formula CnH2n-2 contains one C-C triple bond
halogenoalkanes
homologous series
general formula: CnH2n+1X
halogen present
alcohols
homologous series
general formula: CnH2n+1OH
single hydroxyl group present
