The longest carbon chain in the compound is six carbons, giving us the prefix "hexen". The double bond is located between carbons three and four, so we have "-3-en". There is a methyl group on carbon three and an ethyl group on carbon four, so we have "3-ethyl-4-methyl-". Finally, there is a hydroxyl group on carbon one, giving us the suffix "-1-ol". Putting it all together, we get the name 3-ethyl-4-methyl-3-hexen-1-ol.
