Answer
4-methylcycohex-3-enol
Work Step by Step
1. Find the longest carbon chain with -OH and number it giving -OH the least number.
2. Locate the methyl group
3. Locate the double bond which would be 3.
4. Write the name by dropping e from the name of the longest chain and end with an -ol.
Since methyl is at the 4th carbon, it will be 4-methyl. The double bond is at 3 so cyclohex-3-enol.
