Step 1:
: Identify the first structure as a methane molecule.

Methane: $$CH_4

Step 2:
: The second structure is a hexane molecule, which is a straight-chain alkane with six carbon atoms.

Hexane: $$H-C-C-C-C-C-C-H

Step 3:
: The third structure is another methane molecule.

Methane: $$CH_4

Step 4:
: The fourth structure is a pentane molecule, which is a straight-chain alkane with five carbon atoms.

Pentane: $$H-C-C-C-C-H

Step 5:
: The fifth structure is a neopentane molecule, which is a branched alkane with five carbon atoms.

Neopentane: $$H-C-C-C-C-H$$ (same as pentane but branched)

Step 6:
: The sixth structure is a heptane molecule, which is a straight-chain alkane with seven carbon atoms.

Heptane: $$H-C-C-C-C-C-C-C-H

Step 7:
: The seventh structure is a pentane molecule, which is a straight-chain alkane with five carbon atoms.

Pentane: $$H-C-C-C-C-H

Step 8:
: The eighth structure is a propane molecule, which is a straight-chain alkane with three carbon atoms.

Propane: $$H-C-C-H

Step 9:
: The last structure is an ethane molecule, which is a straight-chain alkane with two carbon atoms.

Ethane: $$H-C-C-H
