give the iupac name for the molecule given below.\nanswer: 2,5-dimethylhept-3-yne

Brief Explanations:

1. Identify the longest carbon chain containing the alkyne triple bond: it has 7 carbons, so the parent chain is heptyne.
2. Number the chain to give the triple bond the lowest possible number: the triple bond is between C3 and C4, so it is hept-3-yne.
3. Locate and name substituents: there are methyl groups at C2 and C5.
4. Combine substituents with the parent chain, listing substituents in alphabetical order (methyl groups are identical, use the prefix "di-") and including their positions.

Answer:

2,5-dimethylhept-3-yne
