Is 3-methyl-4-propyl-3-octene the incorrect nomenclature

Answer 1

Yes, 3-methyl-4-propyl-3-octene is incorrect nomenclature. In organic chemistry, the longest carbon chain should be identified first, and substituents should be named and numbered accordingly. The correct name should reflect the longest continuous chain of carbons, which may require re-evaluating the position of the substituents and the double bond. A proper analysis of the structure would lead to a more accurate systematic name.
