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.

All the butyl groups with different prefixes are used to describe a carbon chain fragment with four carbon atoms, but they differ based on how the atoms are arranged and which carbon is connected to the …

The butyl group is an alkyl substituent with four carbon atoms and nine hydrogen atoms, derived from butane (C 4 H 10) by removing one hydrogen atom. Its general formula is –C 4 H 9, where one …

The meaning of BUTYL is any of four isomeric alkyl radicals C4H9— derived from butane.

Removing a hydrogen atom from the first isomer can result in the formation of two different butyl groups, one designated as n-butyl, and the other as sec-butyl (secondary butyl).

Butane has the molecular formula C 4 H 10, whereas butyl has the molecular formula R – C 4 H 9. The number of carbon atoms is the same, but the number of hydrogen atoms differs slightly.
