Question 1

Which reaction is an oxidation?

Accepted Answer

E

Question 2

Which reagent(s)is/are capable of reducing the following ester to a primary alcohol ?

Accepted Answer

LiAlH4 is a strong reducing agent that can reduce esters to primary alcohols. NaBH4 is a milder reducing agent that can only reduce aldehydes, ketones, and acid chlorides to their respective alcohols, but not esters. Na can reduce the carbonyl group of esters to alcohols, but it would also cause a reduction of any other functional groups present in the molecule, making it less selective. The hydrogenation with H2 and Ni, atmospheric pressure is a viable reducing method, but it is not capable of selectively reducing only the ester group. Therefore, option A is the best choice as it selectively reduces the ester group to the primary alcohol.

Question 3

Which reagent(s)is/are capable of reducing the following ester to an aldehyde ?

Accepted Answer

E

Question 4

Question 8

Which of the following resonance structures is not a significant contributor to the hybrid for the carbonyl group?

Accepted Answer

Resonance structure II is not a significant contributor to the hybrid because it violates the octet rule for the carbon atom, which has only 6 valence electrons. In this structure, the double bond is formed between a carbon atom and a hydrogen atom, which is not possible as hydrogen has only one valence electron that it can share with another atom. Therefore, resonance structure II is unlikely to contribute significantly to the overall hybrid structure of the carbonyl group.

Question 9

Which reagent(s)would you use to convert CH₃(CH₂)₆CO₂H to CH₃(CH₂)₆CH₂OH?

Accepted Answer

This conversion involves the reduction of the carbonyl group to a methylene group. LiAlH4 is a strong reducing agent that can reduce the carbonyl group to a methylene group. The subsequent reaction with H2O will then result in the formation of the alcohol. Option A is incorrect because NaBH4 is only capable of reducing aldehydes and ketones but not carboxylic acids. Option C is incorrect because PCC is an oxidizing agent and would not be able to reduce the carbonyl group to a methylene group. Option D is incorrect because Zn is not a strong enough reducing agent to reduce the carbonyl group to a methylene group. Option E is incorrect because Pt is a catalyst and cannot be used to reduce a carbonyl group.

Question 15

When nucleophilic addition to a carbonyl group occurs,the carbon attacked undergoes this hybridization change:

Accepted Answer

In nucleophilic addition to a carbonyl group, the carbonyl carbon, which is initially sp² hybridized, becomes sp³ hybridized after the nucleophile attacks and forms a tetrahedral intermediate.

Question 16

Accepted Answer

The answer of List the following compounds in order of...

Question 19

The following transformation would be considered a(n)?

Accepted Answer

The presence of TB5901-00, which is likely a reducing agent, suggests that the transformation is an oxidation, as reduction and oxidation are inverse processes. The other answer choices do not necessarily involve redox reactions.
