Question

The major products X and Y respectively from the following reactions are 

• A.
• B.
• C.
• D.

Hint:

When using NaOEt and Mg in dry ether, an ethyl group reacts with the aryl halide to form an ether, which can later be hydrolyzed to form phenol.

Answer 1

The Correct Option is A

In this reaction, the compound reacts with sodium ethoxide (NaOEt) and magnesium (Mg) in dry ether to undergo an addition reaction.
- The first product formed (X) from the reaction of the ethyl group with the aryl halide (Y) results in the formation of an ethoxy group (OEt) attached to the aromatic ring. Thus, X is ethyl phenyl ether (\({C}_6{H}_5{O}{C}_2{H}_5\)).
- The second product (Y) is formed when water is added, resulting in the hydrolysis of the ethoxy group and formation of phenol (\({C}_6{H}_5{OH}\)).
Thus, the major products are:
- X = ethyl phenyl ether (\({C}_6{H}_5{O}{C}_2{H}_5\))
- Y = phenol (\({C}_6{H}_5{OH}\))
Therefore, the correct answer is option (1).

Answer 2

To determine the major products X and Y from the given reactions, we need to analyze the reaction sequence and predict the outcome based on the reagents involved. Unfortunately, image appearances in the options and question are not described in the task. Therefore, I'll provide a generic approach that aids in solving such problems involving organic reactions:

Steps to Predict Reaction Products:

1. Identify Functional Groups: Look at the starting materials and identify any functional groups or reactive sites that may participate in the reaction.
2. Determine Reaction Type: Based on the reagents and conditions provided, assess whether the reactions are substitution, elimination, addition, or rearrangement reactions.
3. Predict Reaction Mechanism: Apply knowledge of organic chemistry mechanisms to predict which bonds are formed and broken, and the movement of electrons in the reaction sequence.
4. Consider Stereochemistry: If applicable, consider any stereochemical implications if the reaction creates chiral centers or involves stereospecific reagents.

For the provided question, assuming it consists of common organic chemistry reactions:

• If the reaction involves a halogenation reagent, it could lead to the substitution or addition of a halogen to an alkene or aromatic compound.
• If a strong base or acid is involved, it might lead to an elimination or protonation reaction.
• If the sequence includes multiple steps, consider intermediate stability and regioselectivity.

The correct answer for this specific problem, as mentioned, corresponds to the solution:

In practice, recognizing the reagents and understanding their typical interactions with given substrates will enable you to deduce the likely products correctly. Mastery of common organic transformations and mechanisms is crucial for solving these kinds of chemistry problems efficiently.
