CH3-CH(CH3)-C≡C-CH2-CH3

The given compound is 2-methyl-2-butyne.

To name the compound:

• Start by identifying the parent chain, which in this case is the longest continuous chain containing the triple bond. It contains 5 carbon atoms, so it is a pentane chain.
• Number the carbon atoms in the chain starting from the end closest to the triple bond. The triple bond is between the third and fourth carbon atoms.
• Identify and name any substituents attached to the parent chain. In this case, there is a methyl group attached to the second carbon atom. So it is a 2-methylpentane chain.
• Finally, indicate the presence of the triple bond by using the suffix "-yne". So the name of the compound is 2-methyl-2-butyne.

I hope this helps! Let me know if you have any other questions.
