Why is Isoprene iso? Isoprene not have its central atom cleaved a hydrogen bond.
« on: May 07, 2024, 01:59:44 PM »



I don't even know what the central atom of a isoprene is. Does the rule above work when you don't have an odd number of carbons on the longest not necessarily straight backbone?

Isoprene is a trivial name for 2-Methyl-1,3-butadiene, i think it has nothing to do with the Iso  like in Iso-propyl. There  is no n-prene vise versa isoprene, like in Isopropyl to n-Propyl or n- Butane and Isobutane (2-Methylpropane).

And?

These are also trivial names.
Please check the IUPAC names for them.

There are also others like Neoprene, Chloroprene, Newprene, Hiprene, Terraprene,etc.
