To determine the correct name for the compound, we can break down the compound into its different parts and analyze them individually.
First, let's identify the longest carbon chain in the compound. Counting the number of carbon atoms in the main chain, we see that it consists of 8 carbon atoms. As a result, the prefix "oct-" should be used to indicate eight carbons.
Next, we need to determine the location of the substituents on the main chain. There are three substituents in the compound: a cyclobutyl group, a dimethyl group, and an alkyne (triple bond).
Starting with the cyclobutyl group, we count the number of carbon atoms in the ring, which is 4. Since the cyclobutyl group is not attached to the main chain directly but through a carbon atom, we need to indicate the position of this attachment. The correct prefix for a cyclobutyl group is "cyclobutyl-", and since it is attached to the 6th carbon atom in the main chain, we use the prefix "6-cyclobutyl-".
Moving on to the dimethyl group, we see that it consists of two methyl (-CH3) groups. To indicate this, we use the prefix "dimethyl-" followed by the location of the two methyl groups on the main chain. Since they are attached to the 2nd and 5th carbon atoms, respectively, we use the prefix "2,5-dimethyl-".
Lastly, we identify the alkyne (triple bond) in the compound. Since it is not directly attached to the main chain but through a carbon atom, we need to indicate the position of this attachment. The correct suffix for an alkyne is "-yne". Since it is attached to the 3rd carbon atom in the main chain, we use the suffix "-3-yne".
Now that we have analyzed all the parts, let's put them together. The proper name for the compound is "6-cyclobutyl-2,5-dimethyl-3-octyne".
Therefore, based on the information provided, the correct answer is (d) 6-cyclobutyl-2,5-dimethyl-3-octyne.
