Question 1

Classify the following molecule:

Accepted Answer

The molecule contains a carbonyl group (C=O) and it is attached to a carbon atom which is bonded to two other carbon atoms, making it a ketone.

Question 2

Which of the following will yield a carboxylic acid upon oxidation?

Accepted Answer

Aldehydes upon oxidation yield carboxylic acids. Secondary alcohols are oxidized to ketones, not carboxylic acids. Cycloalkanes and tertiary alcohols do not readily oxidize to carboxylic acids under normal conditions. Ketones generally require more vigorous conditions for further oxidation and do not typically yield carboxylic acids directly.

Question 3

What alcohols have the greatest commercial value?

Accepted Answer

Methanol and ethanol have the greatest commercial value because they are the most widely produced alcohols and are used in a variety of industrial and consumer applications, such as fuel, solvents, and chemical feedstocks. Phenol, 1-propanol, and other alcohols have more limited uses and lower production volumes.

Question 4

Which molecule is an ether?

Accepted Answer

The molecule CH₃CH₂OCH₃ is an ether because it has an oxygen atom bonded to two alkyl or aryl groups. The other molecules shown either do not have an oxygen atom or do not have it bonded to two alkyl or aryl groups.

Question 5

Which of the following is found in beverages such as wine?

Accepted Answer

Ethanol is the type of alcohol found in beverages such as wine. Methanol, propanol, and isopropanol can also be considered alcohols, but they are not typically found in alcoholic beverages consumed by humans.

Question 6

Which of the following becomes more soluble in water upon addition of NaOH?

Accepted Answer

Carboxylic acids become more soluble in water upon addition of NaOH because they undergo deprotonation to form carboxylate ions, which are more water-soluble.

Question 7

Oxidation of a primary alcohol results in a(n)__________ and oxidation of a secondary alcohol results in a(n)_________.

Accepted Answer

Oxidation of a primary alcohol results in an aldehyde, while oxidation of a secondary alcohol results in a ketone. Therefore, option B is the correct answer.

Question 8

Classify the following molecule:

Accepted Answer

Based on the given molecule, it appears to be a tertiary alcohol. This is because it has three carbon atoms bonded to the hydroxyl group (-OH). A primary alcohol would have only one carbon atom bonded to the -OH group, while a secondary alcohol would have two carbon atoms bonded to the -OH group. The molecule does not have the characteristic structure of an ether or a phenol.

Accepted Answer

The answer of Identify the type of organic compound shown:...

Question 11

Which of the following yields a primary alcohol upon reduction?

Accepted Answer

Aldehydes are reduced to primary alcohols.

Question 12

Which of the following has only one single C-O bond?

Accepted Answer

Alcohol has only one single C-O bond, characterized by the presence of a hydroxyl (-OH) group attached to a carbon atom.

Question 13

Identify the functional group present in the following organic compound:

Accepted Answer

The answer of Identify the functional group present in the...

Question 14

Which molecule is a ketone?

Accepted Answer

The molecule with the formula CH₃CH₂OCH₃ is a ketone. It has a carbonyl group (C=O) in the middle of the molecule, which characterizes a ketone. The other molecules do not have a carbonyl group in the correct position to be considered a ketone.

Question 15

When C₄H₈ is treated with water and H₂SO_4, a tertiary alcohol is produced.Which of the following structures could represent C₄H₈ in this reaction?

Accepted Answer

The answer of When C₄H₈ is treated with water and...

Question 16

Name the following:

Accepted Answer

The name 11eaa8f0_66b9_5240_93a6_bdd3d220c159_TB6423_00 is a random character string that bears no relation to any chemical nomenclature system. Therefore, none of the answer choices can be identified as the correct one.

Question 17

The boiling point of methanol is much higher than that of ethane.This is primarily due to

Accepted Answer

The hydrogen bonding in methanol is the primary reason for its higher boiling point. Methanol has a hydroxyl group that allows for hydrogen bonding to occur between molecules, while ethane does not have any such functional group. Intermolecular hydrogen bonds require more energy to break than the weaker van der Waals forces between ethane molecules, resulting in a higher boiling point for methanol.

Question 18
