Question

Consider the following reaction and identify the product (P).

• A.
• B.
• C.
• D.

Answer 1

The Correct Option is D

To identify the product (P) of the given reaction, we need to analyze the chemical process involved.

The reaction is the Reimer-Tiemann reaction, which is used to form an ortho-formyl phenol from phenol using chloroform (\(\text{CHCl}_3\)) and sodium hydroxide (NaOH). The steps are as follows:

1. The phenol reacts with chloroform in the presence of sodium hydroxide to form a dichlorocarbene intermediate.
2. Phenol is converted to a phenoxide ion under basic conditions, which then attacks the dichlorocarbene intermediate.
3. This results in the formation of an ortho-formylated product after hydrolysis.

Now, let's look at the options provided:

The correct product is the one with an aldehyde (-CHO) group at the ortho position relative to the hydroxyl group.

Thus, the product (P) is:

Hence, the correct answer is the fourth option, which is the ortho-formylated derivative of phenol.
