The double bond gets priority over triple bond. So, the IUPAC name of underset texthex-l-en-5-yne or l-hexene-5-yne overset1CH 2= overset2CH - overset3CH 2- overset4CH 2- overset5C ≡ overset6CH is

Q. IUPAC name of the following is
$C H_{2} = C H - C H_{2} - C H_{2} - C \equiv C H$

$1, 5$ -hexenyne

$1$ -hexene- $5$ -yne

$1$ -hexyne- $5$ -ene

$1, 5$ -hexynene

The double bond gets priority over triple bond.
So, the IUPAC name of
$hex-l-en-5-yne or l-hexene-5-yne C H_{2} 1 = C H 2 - C H_{2} 3 - C H_{2} 4 - C 5 \equiv C 6 H$ is
