<img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-k7derqv7sjycsetj.jpg" /> The double bond is given priority over the triple bond for numbering the chain. Hence, the name will be 2 -methyl pent- 1 -en- 4 -yne.

Q. Choose the correct IUPAC name of the compound:

$4 - M e t h y l - 2 - p e n t e n - 1 - y n e$

$4 - M e t h y l - 4 - p e n t e n - 1 - y n e$

$2 - M e t h y l - 2 - p e n t e n - 4 - y n e$

$2 - M e t h y l - 1 - p e n t e n - 4 - y n e$

The double bond is given priority over the triple bond for numbering the chain. Hence, the name will be $2$ -methyl pent- $1$ -en- $4$ -yne.

Q. Choose the correct IUPAC name of the compound:

4−Methyl−2−penten−1−yne

4−Methyl−4−penten−1−yne

2−Methyl−2−penten−4−yne

2−Methyl−1−penten−4−yne

The double bond is given priority over the triple bond for numbering the chain. Hence, the name will be 2 -methyl pent- 1 -en- 4 -yne.

$4 - M e t h y l - 2 - p e n t e n - 1 - y n e$

$4 - M e t h y l - 4 - p e n t e n - 1 - y n e$

$2 - M e t h y l - 2 - p e n t e n - 4 - y n e$

$2 - M e t h y l - 1 - p e n t e n - 4 - y n e$

The double bond is given priority over the triple bond for numbering the chain. Hence, the name will be $2$ -methyl pent- $1$ -en- $4$ -yne.
