Is It Correct to Name Isopropyl as 1-Methylethyl in IUPAC Nomenclature?

[Swatch]

I was wondering if it's correct to name isopropyl in IUPAC as
1-methylethyl?

There are no structural isomers of propane itself. By itself, isopropyl is nothing really--->just the same ol' n-propane. Isopropyl bonded as an alkyl group to something else is really just propane bonded to that something else via its second carbon (carbon #2). For example, that's why we say "isopropyl alcohol" as equivalent to "2-propanol". (or isopropanol)

As for the nomenclature, why would you name propane as 1-methylethane ? Propane itself can only exist as an n-alkane. Ethylethane is n-butane, but we just say n-butane.

Yes, it is correct to name isopropyl as 1-methylethyl in IUPAC nomenclature. Isopropyl is a common name for the 1-methylethyl functional group, which consists of a carbon atom attached to two other carbon atoms, one of which is attached to three hydrogen atoms and the other is attached to one hydrogen atom. In IUPAC nomenclature, the parent chain is named as propane, and the substituent group (1-methylethyl) is placed as a prefix before the parent chain. Therefore, 1-methylethyl is the preferred IUPAC name for isopropyl.
