Naming

Postby Anjali_U_3L » Mon Mar 06, 2017 3:58 pm

Is propan-2-one an accepted IUPAC name or can it only be 2-propanone?

I think that for more complicated alkenes and alkynes, it's acceptable to write the number before the infix. For example in the book, 2-pentyne can also be named pent-2-yne.
Since 2-propanone doesn't have double or triple bonds and is a fairly simple molecule, I don't think it should be named pronan-2-one
