organic chemistry - Which is the correct way to name pentan-3-one?

I have seen this organic compound named in two different ways.

According to some sources it is written pentan-3-one.. Other sources call it 3-pentanone.

Which one is correct?

Answer

Whether you write pentan-3-one or 3-pentanone both are correct.

But according to IUPAC rule pentan-3-one this is correct format of writing the name of organic compound. So I prefer you to write pentan-3-one rather than 3-pentanone.
