Butyl group
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: CH3−CH2−CH2−CH2− (preferred IUPAC name: butyl)
- If it connects at one of the non-terminal (internal) carbon atoms, it is secondary butyl or sec-butyl: CH3−CH2−CH(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, it is isobutyl: (CH3)2CH−CH2− (preferred IUPAC name: 2-methylpropyl)
- If it connects at the central carbon, it is tertiary butyl, tert-butyl or t-butyl: (CH3)3C− (preferred IUPAC name: tert-butyl)
