Answer
- Pent-4-en-2-one
The IUPAC name for the given compound is Pent-4-en-2-one.
The parent hydrocarbon contains 5 C atoms. Hence, the compound is a derivative of pentane. A C=O group is present at second C atom.
Hence the last alphabate 'e' of pentane is replaced with 2-one to obtain pentan-2-one.
There is one C=C double bond between fourth and fifth carbon atom. Hence -an- in pentan-2-one is replaced with 4-en.
Hence, the correct IUPAC name is Pent-4-en-2-one.
