These common names make use of prefixes, such as iso-, sec-, tert-, and neo-.The prefix iso-, which stands for isomer, is commonly given to 2-methyl alkanes.In other words, if there is methyl group located on the second carbon of a carbon chain, we can use the prefix … The opposite of neo is paleo . They are commercially very important, for being the principal constituent of gasoline and lubricating oils and are extensively employed in organic chemistry; though the role of pure alkanes (such as hexanes) is delegated mostly to solvents. Radicals are the side chains obtained from the removal of hydrogen from the corresponding hydrocarbon. The prefix “neo” is used when all but two carbons form a continuous chain, and these two carbons are part of a terminal tert-butyl group Common name: neopentane IUPAC name: 2,2-dimethylpropane These branches occur at the end of the molecule. look the prefix r used for isomers of organic compound. ... prefix New. Alkanes are the simplest and the least reactive hydrocarbonspecies containing only carbons and hydrogens.
