Homework Statement

Which name is more correct, 2-oxo-cyclopentanitrile or 2-cyano-cyclopentanone

2. The attempt at a solution
The priority of CN group is higher than ketone, so the first name should be correct but the second name is mentioned in my textbook

Your book is wrong:

However, IUPAC also says that a chemical name is acceptable as long as it's unambiguous, so either one would work in practice.
