Phar 220 Functional Groups

The correct answer, primary amide, is a specific type of compound with distinct characteristics related to its neutrality, lack of ionization, and solubility in water. The three incorrect answers provided are different types of compounds with their own unique properties that distinguish them from primary amides.

A secondary amide is neutral, non-electrolyte, and has good water solubility due to its molecular structure. Primary alcohols are acidic, electrolytes, and have poor water solubility. Tertiary amines are basic, electrolytes, and have moderate water solubility. Quaternary ammonium salts are basic, electrolytes, and have low water solubility.

The correct answer is tertiary amide because it describes the compound's properties accurately, such as being neutral, a non-electrolyte, and having good water solubility.

Pyrrolidine fits the description provided in the question as a weak base that is ionizable, water soluble, and very reactive.

Piperidine is the correct answer as it is a weak base, ionizable, water soluble, and very reactive. Ethanol, methane, and acetic acid do not match the given chemical formula.

Piperazine is the correct answer because it fits the description provided in the question as a weak base that is ionizable, water soluble, and very reactive. Acetaminophen, ammonium, and benzene do not share these characteristics.

The correct answer is hexahydroazepine, as it accurately represents the chemical compound with its characteristics. The incorrect answers provided are different chemical compounds with varying properties, making them incorrect choices for this question.

Morpholine fits the description of being a weak base, ionizable, water soluble, and very reactive. Pyrrole, piperidine, and triazole do not possess all these characteristics.

Carbonate is a compound with a specific name and chemical properties, different from other compounds listed as incorrect answers which have their own unique characteristics.

Urea is a type of carbamate which is neutral and considered a nonelectrolyte, unlike the other options which are either acidic, basic, or exhibit electrolyte properties.

Amidines are known for being very basic, ionizable, and very soluble. They possess a positively charged nitrogen atom that contributes to their basic nature and ability to readily form ions in solution.

Guanidine fits the description of being a very basic, ionizable, and very soluble compound, making it the correct answer.

Oxirane is also known as ethylene oxide, it is a cyclic ether and commonly used as a sterilizing agent in healthcare facilities due to its reactivity.

Tetrahydrofuran is a chemical compound with a tetrahedral structure that causes significant ring strain, making it very reactive in various chemical reactions. The incorrect answers provided are different chemicals with distinct properties that do not match the reactivity of tetrahydrofuran.

Sulphonamide is the correct answer as it is a weak acid, ionizable, and contains an acidic nitrogen due to resonance, making it a distinct chemical compound. The other incorrect options do not match these specific characteristics of sulphonamide.

Sulfonic acid is a weak acid that can ionize in solution, forming hydrogen ions (H+) and the conjugate base. Acetic acid, hydrochloric acid, and nitric acid are not sulfonic acids and therefore are not the correct answer to this question.

Thiol is a type of functional group containing sulfur bonded to a hydrogen atom. It is considered a weak acid due to the ionization of the sulfur-hydrogen bond.

A cyclic ester is referred to as a lactone ring in chemistry terminology.

A lactone ring is a cyclic ester compound, commonly found in antibiotics, that is known for its reactivity due to the strain in the ring structure.

A lactam ring is a cyclic amide, often found in antibiotics. It is neutral, making it a nonelectrolyte. Lactam rings are very reactive due to the strain caused by the ring structure.

Phenol is a compound that functions as a weak acid, is ionizable, and is not classified as an alcohol. It is water-soluble, unlike the incorrect answers provided.

Aniline is a chemical compound that is commonly used in the production of dyes and plastics due to its ionizable properties as a weak base.

Hydroquinone is the correct answer as it is a weak acid, ionizable, and water soluble. The incorrect answers are ethanol, methane, and acetic acid, each with different properties that do not match those of hydroquinone.

o-cresol is the correct chemical name for the compound mentioned. It is a weak acid, ionizable, and water soluble. The other options provided are different compounds that are not synonymous with o-cresol.

Resorcinol is a weak acid that is ionizable and water-soluble, making it different from methanol, acetone, and benzene which are not weak acids and have different properties.

Imide refers to a compound with a weak acid character and is ionizable. The presence of an acidic nitrogen is attributed to the resonance of the lone pair on nitrogen, leading to its acidic properties.

Pyridine is a weak base that is ionizable due to its nitrogen atom with a lone pair of electrons, allowing it to accept a proton.

Pyrazine is a weak base that is ionizable due to the presence of nitrogen atoms in its structure.

Pyridazine fits the description provided as a weak base that is ionizable.
