sekbutüülrühm
Sekbutüülrühm is a branched alkyl group with the chemical formula C4H9. It is one isomer of the butyl group, meaning it has the same number of carbon and hydrogen atoms but a different structural arrangement. In the sekbutüülrühm, the attachment point to the main molecule is on the second carbon atom of a four-carbon chain. This carbon atom is bonded to one methyl group, one ethyl group, and the rest of the molecule. The systematic IUPAC name for the sekbutüülrühm is sec-butyl.
The physical and chemical properties of compounds containing a sekbutüülrühm are influenced by its branched structure.
