Which of the following statements accurately describes carboxylic acids?

Carboxylic acids contain a carbonyl group bonded to an oxygen atom and a hydroxyl group bonded to the same carbon atom.

Carboxylic acids are organic compounds containing a carboxyl group, which consists of a carbonyl group bonded to a hydroxyl group.

Carboxylic acids are characterized by the presence of a double bond between a carbon and an oxygen atom, along with a hydroxyl group.

Carboxylic acids are inorganic compounds that contain a carboxylate ion, consisting of a carbon atom bonded to three oxygen atoms.

Which of the following statements accurately describes alcohols?

Alcohols are organic compounds containing a carboxyl group, which consists of a carbonyl group bonded to a hydroxyl group.

Alcohols are organic compounds containing a hydroxyl group (-OH) bonded to a carbon atom.

Alcohols are inorganic compounds consisting of a carbon atom bonded to three oxygen atoms.

Alcohols are characterized by the presence of a double bond between a carbon and an oxygen atom, along with a hydroxyl group.

Which of the following statements accurately distinguishes between aldehydes and ketones?

Aldehydes have a carbonyl group bonded to a hydrogen atom, while ketones have a carbonyl group bonded to a carbon atom in the middle of the chain.

Aldehydes and ketones both have a carbonyl group bonded to a carbon atom, but aldehydes have a double bond between the carbon and oxygen atoms, while ketones have a single bond.

Aldehydes and ketones both have a carbonyl group, but aldehydes always have one alkyl group bonded to the carbonyl carbon, while ketones have two alkyl groups.

Aldehydes and ketones are both functional groups that contain a carbonyl group, but they differ in the placement of the carbonyl group within the molecule: aldehydes have the carbonyl group at the end of the carbon chain, while ketones have it in the middle.

Which of the following statements accurately distinguishes between alkanes and alkenes?

Alkanes are saturated hydrocarbons containing only single bonds between carbon atoms, while alkenes are unsaturated hydrocarbons containing at least one carbon-carbon double bond.

Alkanes are unsaturated hydrocarbons containing at least one carbon-carbon double bond, while alkenes are saturated hydrocarbons containing only single bonds between carbon atoms.

Alkanes and alkenes both contain carbon-carbon triple bonds, but alkanes have fewer hydrogen atoms bonded to each carbon atom compared to alkenes.

Alkanes and alkenes are both saturated hydrocarbons containing only single bonds between carbon atoms, but alkenes have a higher melting point than alkanes.

Which of the following BEST describes ester bonds?

Ester bonds are formed between two amino acids in a protein chain.

Ester bonds are formed by the dehydration synthesis reaction between a carboxylic acid and an alcohol, resulting in the elimination of water.

Ester bonds are found in the backbone of nucleic acids, linking nucleotides together.

Ester bonds are commonly found in the structure of carbohydrates, providing energy storage in living organisms.
