Question

IUPAC name of the following is CH 2= CH - CH 2- CH 2- C ≡ CH (A) 1, 5-hexenyne (B) 1-hexene-5-yne (C) l-hexyne-5-ene (D) 1, 5-hexynene

The double bond gets priority over triple bond. So, the IUPAC name of overset1CH2= overset2CH- overset3CH2- overset4CH2- overset5C≡ overset6CH is hex-1-en-5-yne or 1-hexene-5-yne

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

l-hexyne-5-ene

1, 5-hexynene

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