Answer:

3-ethyl-1-hexyne or 4-ethyl-1-hexyne.

Explanation:

Hello,

By means of the more likely reagents to undergo the stated hydrogentation via catalysis with palladium or platinum, its structure is shown on the attached picture which is eligible for either 3-ethyl-1-hexyne or 4-ethyl-1-hexyne since they lead to the very same product. Do not forget that such hydrogenation covers up all the insaturations turning out into the specified alkane.

Best regards.
