The exact chemical formula for 1-chloro-2-methylbutane is C₅H₁₁Cl.
Understanding the Molecular Structure of 1-Chloro-2-methylbutane
The name "1-chloro-2-methylbutane" follows the systematic IUPAC nomenclature, which clearly describes its molecular structure:
- Butane: This forms the backbone of the molecule, indicating a parent chain of four carbon atoms.
- 2-methyl: A methyl group (–CH₃), consisting of one carbon atom and three hydrogen atoms, is attached to the second carbon atom of the butane chain.
- 1-chloro: A chlorine atom (–Cl) is attached to the first carbon atom of the butane chain. This substituent replaces one hydrogen atom.
Considering these components, the total number of carbon atoms is five (four from the butane chain plus one from the methyl group). The compound can be thought of as a pentane isomer (C₅H₁₂) where one hydrogen atom has been substituted by a chlorine atom. This substitution reduces the number of hydrogen atoms by one while adding a chlorine atom, leading to the overall formula C₅H₁₁Cl. This compound is categorized as an alkyl halide.
