Chemical group (−C₄H₉) derived from butane

"Butyl" redirects here. For the synthetic rubber, see Butyl rubber.

In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula

−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:

If it connects at one of the three terminal carbons, i...
