Lipids do not store genetic information; that function is performed by nucleic acids.

While proteins can be involved in energy metabolism, they are not primarily used for energy storage; carbohydrates and fats serve that purpose.

Elastomers typically do not have good thermal stability; they are more flexible and can return to their original shape after deformation.

Brittleness is generally not a property of polymers; they are usually more flexible.

Hydrogen isomerism is not a recognized type of isomerism in chemistry.

Cyclooctatetraene is not aromatic because it does not satisfy Huckel's rule; it is non-planar and does not have a continuous overlap of p-orbitals.

Ethyne, also known as acetylene, has the formula C2H2, which indicates it is an alkyne.

The compound is a ketone with a four-carbon chain, and the carbonyl group is on the second carbon, hence it is Butan-2-one.

C3H6 corresponds to propene, which is an alkene with a double bond.

The compound has 3 carbons in the longest chain and a carboxylic acid group, hence it is Propanoic acid.

C5H10 corresponds to pentane, which is a straight-chain alkane with 5 carbon atoms.

C6H12 is a straight-chain alkane with 6 carbons, which is named Hexane.

The compound has a phenyl group attached to a butanoic acid structure, making it Phenylbutanoic acid.

The compound has a phenyl group attached to an ethyl group, making it Ethylbenzene.

The longest carbon chain has 5 carbons, and there is a methyl group on the second carbon, making it 2-Methylbutane.

The longest chain has four carbons, and the hydroxyl group is on the first carbon, with a methyl group on the second carbon, making it 2-Methylbutan-1-ol.

The correct IUPAC name for CH3CH2CH2OH is Butan-1-ol, as it has four carbon atoms with the hydroxyl group on the first carbon.

The correct IUPAC name for CH3CHO is Ethanal.

The compound CH3COOH is known as Ethanoic acid, which is the IUPAC name for acetic acid.

The compound is an aldehyde with two carbons, hence the IUPAC name is Ethanal.

C3H6O can be identified as Propanal, which is an aldehyde with three carbons.

The longest chain has 5 carbons, with a methyl group on the second carbon and a carboxylic acid on the first, making it 3-Methyl-2-pentanoic acid.

The compound has a triple bond and the longest chain has five carbons, making it 3-Methyl-1-pentyne.

The compound has a hydroxyl group on the second carbon of a four-carbon chain, making it 2-Butanol.

The compound has a four-carbon chain with an aldehyde functional group, so it is named Butanal.

The compound is a carboxylic acid with 5 carbons, named Pentanoic acid.

The compound has three carbons in the longest chain and a carboxylic acid functional group, making it Propanoic acid.

The compound is a straight-chain alkane with five carbons, hence the name is Pentane.
