−C4H9, derived from either of the two isomers (n-butane and isobutane) of butane.The isomer n-butane can connect in two ways, giving rise to two "-butyl" groups:
If it connects at one of the two terminal carbon atoms, it is normal butyl or n-butyl: −CH2−CH2−CH2−CH3 (preferred IUPAC name: butyl) If it connects at one of the non-terminal (internal) carbon atoms, it is secondary butyl or sec-butyl: −CH(CH3)−CH2−CH3 (preferred IUPAC name: butan-2-yl)The second isomer of butane, isobutane, can also connect in two ways, giving rise to two additional groups:
