Write the iupac name ?
Solution
While naming an IUPAC compound, numbering should start from that end from where functional group gets lowest number. In the given compound, ketone is the functional group and therefore, numbering should start from right end.
The parent chain has 10 carbon atoms, so, the word root will be "dec". A substituent "1-methyl ethyl" is present at 6th carbon which will be added as prefix. A double bond is present between 7th and 8th carbon atoms and ketone is present at 5th carbon atom, so the suffix will be "7-en-5-one".
Therefore, the IUPAC name of the compound will be "6-(1-methylethyl)dec-7-en-5-one".
