What is the correct IUPAC name of the hydrocarbon with the structure ? — Hydrocarbons Chemistry Question

💡 Solution & Explanation

The longest continuous carbon chain containing the double bond has four carbon atoms, so the parent name is butene. Numbering from the end closer to the double bond gives the double bond position 1. There are methyl groups at positions 2 and 3. Therefore, the IUPAC name is 2,3-dimethylbut-1-ene.
