butil
Butyl is a term commonly used in chemistry to refer to a group of four related alkyl radicals derived from butane, a four-carbon alkane. These radicals are structural isomers, meaning they have the same molecular formula (C₄H₉) but differ in the arrangement of their carbon atoms. The four primary butyl groups are n-butyl, sec-butyl, isobutyl, and tert-butyl, each distinguished by the position of the branching in their carbon chains.
The n-butyl (normal-butyl or straight-chain butyl) group is a linear chain of four carbon atoms (CH₃CH₂CH₂CH₂–).
The isobutyl group has a branching at the first carbon (CH(CH₃)₂CH₂–), creating a three-carbon chain with a
Butyl compounds are also found in various industrial applications, including fuels, lubricants, and adhesives. Their reactivity
