Question

IUPAC name of the following is CH2=CH-CH2-CH2-C≡ CH (A) 1, 5-hexenyne (B) 1-hexene-5-yne (C) 1-hexyne-5-ene (D) 1, 5-hexynene

The double bond gets priority over triple bond. So, the IUPAC name of overset1CH 2= overset2CH - overset3CH 2- overset4CH 2- overset5C ≡ overset6CH is Hex-1-en-5-yne or l-hexene-5-yne.

Q. $I U P A C$ 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 $I U P A C$ 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 l-hexene-5-yne.
