What is the general formula of homologous series of alcohol? |
|
Answer» each alcohol group differ by CH2 CnH2n+1-OH Name of Serie General chemical formula\tAlkanes CnH2n+2\tAlkenes CnH2n\tAlkynes CnH2n-2\t1-bromoalkanes\t(e.g. of Haloalkanes) CnH2n+1Br\t1-alcohols\t(e.g. of Alcohols) CnH2n+1OH = CnH2n+2O\tAldehydes CnH2nO\tCarboxylic Acids CnH2nO2\tAcid Chlorides CnH2n-1OCl\tAmines CnH2n+1NH2 = CnH2n+3N\tAmides CnH2n-1ONH2 = CnH2n+1ON\tNitriles CnH2n-3Nwhere n represents the number of carbon atoms in the chain. Note that in some cases the minimum value of the number of carbons in the chain (n) is greater than 1 (n>1).For example, ethene (2 carbons) is the smallest alkene and ethanenitrile (2 carbons) is the smallest nitrile.
