MCQ
The $\text{IUPAC}$ name of the compound $\mathrm{CH} \equiv \mathrm{C}-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{CH}=\mathrm{CH}_2$ is :
- ✓Hex $-1-$ en $-5-$ yne
- BHexyn $-5-$ ene
- CHex $-5-$ en $-2-y$ ne
- DHex $-5-$ en $-1-$ yne
✓
Answer
Correct option: A.
Hex $-1-$ en $-5-$ yne
$\mathrm{CH} \equiv \mathrm{C}-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{CH}=\mathrm{CH}_2$
$\text{IUPAC}$ name : Hex $-1-$ en $-5-$ yne.
Numbering starts from the double bond bearing carbon, as alkenes are higher priority functional groups than alkynes $($triple bond$).$
