It is an alkane, and one of the many structural isomers of heptane, consisting of a five carbon chain with a two carbon branch at the middle carbon. An example of an alcohol derived from 3-ethylpentane is the tertiary alcohol 3-ethylpentan-3-ol.[2] References1. ^{{Cite web|title=3-ETHYLPENTANE - Compound Summary|url=https://pubchem.ncbi.nlm.nih.gov/summary/summary.cgi?cid=12048&loc=ec_rcs|work=PubChem Compound|publisher=National Center for Biotechnology Information|accessdate=5 March 2012|location=USA|date=26 March 2005|at=Identification and Related Records}} {{DEFAULTSORT:Ethylhentane, 3-}}{{Hydrocarbon-stub}}2. ^Ritchie, R and Gent, D: OCR Chemistry AS, page 151.
