IUPAC name of the following is $\mathrm{CH}_2=$ $\mathrm{CH}-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{C} \equiv \mathrm{CH}$ :
1, 5-hexenyne
1-hexene 5-yne
1-hexyne-5-ene
1,5-hexynene
Solution
The IUPAC name of $\mathrm{CH}_2 \mathrm{CHCH}-$ ${ }_2 \mathrm{CH}_2 \mathrm{CCH}$ is 1-hexene-5-yne
The double bond gets priority over triple bond in IUPAC nomenclature.
