Question 1

Which of the following is the substance that causes the symptoms associated with a 'hangover'?

Accepted Answer

Ethanal (acetaldehyde) is the primary substance responsible for the symptoms associated with a 'hangover'. It is produced when the liver metabolizes ethanol (alcohol), and its accumulation in the body can lead to the unpleasant symptoms experienced during a hangover.

Question 2

Which of the following substances can be used to produce a chemical tan?

Accepted Answer

Dihydroxyacetone (DHA) is used in self-tanning products to produce a chemical tan by reacting with the amino acids in the dead layer on the skin surface, creating a brown color.

Question 3

Which of the following is an ingredient in some inhalants?  It has a characteristic medicinal odor.

Accepted Answer

Camphor is known for its strong, medicinal odor and is an ingredient in some inhalants, often used for its therapeutic properties in relieving congestion and coughs.

Question 4

Which of the following properly ranks the relative aqueous solubility of each functional group?

Accepted Answer

Alcohols have the highest aqueous solubility due to their ability to form hydrogen bonds with water. Aldehydes and ketones have moderate solubility because of their polar carbonyl group, but cannot hydrogen bond as effectively as alcohols. Alkenes have the lowest solubility because they are nonpolar.

Question 5

Accepted Answer

The answer of Our bodies rely on a two step...

Question 7

Which of the following has the highest boiling point?

Accepted Answer

Butanal has the highest boiling point among the options given. This is because boiling point increases with molecular weight or size, and butanal, being the largest molecule among the choices, has the highest boiling point.

Question 8

Which of the following will give both a positive Tollens' test and a positive Benedict's test?

Accepted Answer

The answer of Which of the following will give both...

Question 9

What is the common name for 2-butanone?

Accepted Answer

2-butanone is commonly known as methyl ethyl ketone (MEK) because its structure consists of a ketone group attached to an ethyl group and a methyl group.

Question 10

Which of the following is a condensed structural formula for an aldehyde? (Note: R is used to represent a generic alkyl chain).

Accepted Answer

Aldehydes have the general formula RCHO, where R represents an alkyl group and CHO indicates the aldehyde functional group (carbonyl group bonded to a hydrogen atom).

Question 11

Which of the following is a structural representation of benzaldehyde?

Accepted Answer

The answer of Which of the following is a structural...

Question 12

Oxidation of an aldehyde will produce?

Accepted Answer

Oxidation of an aldehyde results in the formation of a carboxylic acid. This is because the aldehyde group (R-CHO) is further oxidized to a carboxyl group (R-COOH).

Question 13

An unknown compound undergoes no change under oxidizing conditions but reacts readily with hydrogen in the presence of a Pt catalyst.  Which of the following might be this unknown compound?

Accepted Answer

The answer of An unknown compound undergoes no change under...

Question 14

Formaldehyde is a ____ at room temperature.

Accepted Answer

Formaldehyde is a gas at room temperature, but it is often used and stored in an aqueous solution known as formalin.

Question 15

The intermediate product of two moles of a primary alcohol and one mole of a ketone would be a(n)____.

Accepted Answer

The reaction of a primary alcohol with a ketone initially forms a hemiketal as the intermediate product.

Question 16

Norethynodrel is a common drug used for birth control. Which of the following is NOT a common side affect associated with norethynodrel?

Accepted Answer

Weight loss is not commonly associated with norethynodrel; instead, weight gain is more typical.

Question 17

Which of the following substances is an integral portion of embalming fluid?

Accepted Answer

Methanal, also known as formaldehyde, is a key component of embalming fluid, used for its preservative and disinfectant properties.

Question 18

Fully reacting an aldehyde with an alcohol will produce?

Accepted Answer

Fully reacting an aldehyde with an alcohol under acidic conditions leads to the formation of an acetal. This involves the conversion of the carbonyl group of the aldehyde to an acetal through a nucleophilic addition reaction, where two equivalents of alcohol react with the aldehyde.

Question 19

Which of the following is NOT a proper IUPAC name?

Accepted Answer

In IUPAC nomenclature, the carbonyl carbon of a ketone is assigned the lowest possible number. For pentanone, the carbonyl group can be at the 2-position (2-pentanone) or at the 3-position (3-pentanone) since numbering from either end of the chain gives the same result. "1-pentanone" is incorrect because the carbonyl group in a ketone cannot be at the terminal position (that would make it an aldehyde, not a ketone). "1-cyclopentanone" is correct because in cyclic ketones, the carbonyl carbon is automatically assigned the number 1.

Question 20

Hydrogenation of an aldehyde will produce?

Accepted Answer

Hydrogenation of an aldehyde reduces the carbonyl group to an alcohol group, specifically forming a primary alcohol.
