Quick Summary

2,3-dimethylbutane is a chemical compound with the formula C₆H₁₄. It is an isomer of hexane, meaning it has the same chemical formula but a different structural arrangement of atoms. Specifically, it is a branched-chain alkane where two methyl groups (CH₃) are attached to the second and third carbon atoms of a butane chain.12

This compound can exist as stereoisomers, which are molecules with the same formula but different spatial arrangements of atoms. In the case of 2,3-dimethylbutane, it can form enantiomers (non-superimposable mirror images) and a meso compound (an achiral molecule with stereogenic centers) due to its structure.2
