Question

What are the isomers of C3H6O?

Answer 1

I count 11 isomers of `"C"_3"H"_6"O"`.

Explanation:

They are:

Prop-2-en-1-ol

Methoxyethene

Propanone

(from www.meritnation.com)

And its tautomer,

Prop-1-en-2-ol

Propanal

(from commons.wikimedia.org)

And its two tautomeric isomers

(`Z`)-Prop-1-en-1-ol

and

(`E`)-Prop-1-en-1-ol

Then we have

Cyclopropanol

Oxetane

(`R`)-Methyloxirane

(`S`)-Methyloxirane

And that makes 11 isomers!
