Naming the Molecules

The given molecules are: 1. H3C-C≡C-CH3 2. H3C-CH=CH2 3. H3C-CH2-CH3

To provide the names for each molecule, we need to follow the rules of IUPAC nomenclature for organic compounds.

1. H3C-C≡C-CH3: - The molecule has a triple bond between the second and third carbon atoms. - The first carbon atom is attached to three hydrogen atoms, and the last carbon atom is attached to three hydrogen atoms. - Therefore, the name of this molecule is 1-ethyne.

2. H3C-CH=CH2: - The molecule has a double bond between the second and third carbon atoms. - The first carbon atom is attached to three hydrogen atoms, and the last carbon atom is attached to two hydrogen atoms. - Therefore, the name of this molecule is 1-propene.

3. H3C-CH2-CH3: - The molecule has a single bond between each carbon atom. - The first carbon atom is attached to three hydrogen atoms, and the last carbon atom is attached to three hydrogen atoms. - Therefore, the name of this molecule is propane.
