Which of the following compounds is classified as a secondary alcohol?

Accepted Answer

2-Propanol

Question 3

What is the IUPAC name for the following compound: $$CH_3CH_2CH(OH)CH_3$?

Accepted Answer

2-Butanol

Question 4

Which of the following best describes the difference in physical properties between alcohols and ethers of similar molecular mass?

Accepted Answer

Alcohols have higher boiling points due to hydrogen bonding.

Question 5

A student is given a compound with the formula $$C_3H_8O. $$Which of the following is a possible IUPAC name for this compound if it is an ether?

Accepted Answer

Methoxyethane

Question 6

Which of the following reactions will occur when phenol is mixed with aqueous sodium hydroxide ($$NaOH$$)?

Accepted Answer

Phenol will react to form a phenoxide ion and water.

Question 7

Which of the following best explains why primary alcohols generally have higher boiling points than alkanes of similar molar mass?

Accepted Answer

Primary alcohols can form strong hydrogen bonds, while alkanes cannot.

Question 8

What is the product when 1-butanol is heated with concentrated sulfuric acid?

Accepted Answer

1-Butene

Question 9

Which of the following statements about the oxidation of alcohols is correct?

Accepted Answer

Primary alcohols can be oxidized to aldehydes and then to carboxylic acids.

Question 10

Which of the following is the correct IUPAC name for a compound with two hydroxyl groups on a propane backbone?

Accepted Answer

1,2-Propanediol

Question 11

A patient is exposed to methanol ($$CH_3OH). $$Which of the following best explains the medical risk associated with methanol ingestion?

Accepted Answer

Methanol is oxidized in the body to formaldehyde and formic acid, which are toxic.

Question 12

Which of the following best describes the difference between the chemical properties of alcohols and phenols?

Accepted Answer

Phenols are more acidic and can react with strong bases to form phenoxide ions, while alcohols are much less acidic.

Question 13

Which of the following best explains why the boiling point of alcohols increases as the molecular mass increases?

Accepted Answer

Larger alcohol molecules have greater London dispersion forces in addition to hydrogen bonding.

Question 14

Which of the following is the correct IUPAC name for $$CH_3CH_2SCH_3$$?

Accepted Answer

Ethyl methyl sulfide

Question 15

Which of the following statements about thiols is correct?

Accepted Answer

Thiols have lower boiling points than alcohols of similar mass due to weaker hydrogen bonding.

Question 16

Which of the following is the correct product when 2-propanol is oxidized?

Accepted Answer

Acetone ($$CH_3COCH_3)$$

Question 17

Which of the following best describes the dehydration reaction of alcohols?

Accepted Answer

An alcohol loses a water molecule to form an alkene.

Question 18

Which of the following is the correct classification for the alcohol group in 2-methyl-2-propanol?

Accepted Answer

Tertiary alcohol

Question 19

Which of the following is the correct IUPAC name for $$CH_3CH_2CH_2SH$$?

Accepted Answer

1-Propanethiol

Question 20

A chemist wants to synthesize an ether by reacting two alcohols. Which of the following pairs of alcohols would produce diethyl ether ($$CH_3CH_2OCH_2CH_3) $$upon dehydration?

Accepted Answer

Two molecules of ethanol
