$$IUPAC$$ name of the following is
$$C{H_2} = CH - C{H_2} - C{H_2} - C \equiv CH$$
A.
$$1, 5-hexenyne$$
B.
$$1-hexene-5-yne$$
C.
$$1-hexyne-5-ene$$
D.
$$1, 5-hexynene$$
Answer :
$$1-hexene-5-yne$$
Solution :
The double bond gets more priority over triple bond. So, the $$IUPAC$$ name of compound is
$$\mathop {C\mathop {{H_2}}\limits^1 = C\mathop H\limits^2 - C\mathop {{H_2}}\limits^3 - C\mathop {{H_2}}\limits^4 }\limits_{hex - 1 - en - 5 - yne{\text{ or }}1 - hexene - 5 - yne} - \mathop C\limits^5 \equiv \mathop C\limits^6 H$$
