Aldehyde when used as side chain, can indicated any of the two prefixes according to situation. chloroethane The position of the functional group on the carbon chain is given by a number - counting from the end of the molecule that gives the functional group the lowest number. Ba sic knowledge of the structures and polarities of these groups is assumed. The smallest organic nitrile is ethanenitrile, CH 3 CN, (old name: methyl cyanide or acetonitrile - and sometimes now called ethanonitrile). What are nitriles? The nitrile group is a carbon triple-bound to a nitrogen atom, where the carbon rather than the nitrogen is attached to the parent chain. Functional groups determine the characteristic physical, chemical and biological properties of a molecule. But, carboxylic acid has higher priority than the -OH, thus -OH will appeared in the name of the compound as the prefix - hydroxy.
