Question

Whether Propan-2-ol & Propane-2-ol are same? ​

Answer 1

Yes both are of same structure ISOMERS

Answer 2

Both are same. But according to IUPAC nomenclature rules, the correct name would would be propan-2-ol. We drop the 'e' from propane because the suffix 'ol' begins with a vowel. Though by saying either one, you technically refer to the same compound but it is better to use propan-2-ol.
