The 2004 IUPAC names for alkyl groups are derived from the alkane having the same carbon chain as the alkyl group. The -e ending of that alkane is replaced by - yl, and the chain is numbered from the end that gives the carbon at the point of attachment its lower number. This number immediately precedes the - yl ending and is bracketed by hyphens.  

 Name the C4H9 alkyl groups according to this system.
