which of following alcohols can be oxidized to be a carboxylic acid. Name the carboxylic acid produced. Those that cannot be oxidized to a carboxylic acid name the final product

A. ethanol
b. 2-propanol
c. 1-propanol
d. 3-pentanol

A and C can be oxidized to form carboxylic acids, and the rest of them will form ketones.

Why are we deprotonating the carboxylic acid that is initially dissolved in the dichloromethane?


By deprotonating the carboxylic acid, it becomes soluble in the aqueous HCl extracting layer.

By deprotonating the carboxylic acid, it becomes soluble in the aqueous NaOH extracting layer.

There is no deprotonation taking place. The carboxylic acid is simply more soluble in the extracting HCl layer.

To determine which alcohols can be oxidized to form a carboxylic acid, we need to first understand the oxidation reactions of alcohols.

Alcohols can undergo oxidation reactions, where they lose hydrogen and gain oxygen. This process converts the alcohol functional group (-OH) to a carbonyl group (C=O). If the oxidation reaction continues, the carbonyl group can be further oxidized to a carboxylic acid functional group (COOH).

Let's analyze each alcohol from the options you provided:

A. Ethanol:
Ethanol can be oxidized to form acetic acid (also known as ethanoic acid), which is a carboxylic acid.

B. 2-Propanol:
2-Propanol can also be oxidized to form acetone (also known as propanone). Acetone is not a carboxylic acid; it is a ketone, which is a compound containing a carbonyl group, but without the presence of a carboxylic acid functional group.

C. 1-Propanol:
1-Propanol can be oxidized to form propanoic acid, which is a carboxylic acid.

D. 3-Pentanol:
3-Pentanol can also be oxidized, but instead of forming a carboxylic acid, it would produce a ketone called 3-pentanone. As mentioned before, ketones do not have a carboxylic acid functional group.

In summary:
A. Ethanol can be oxidized to form acetic acid (a carboxylic acid).
B. 2-Propanol can be oxidized to form acetone (a ketone).
C. 1-Propanol can be oxidized to form propanoic acid (a carboxylic acid).
D. 3-Pentanol can be oxidized to form 3-pentanone (a ketone).

Remember, the oxidation of alcohols to carboxylic acids typically requires a strong oxidizing agent, such as potassium permanganate (KMnO4) or chromium(VI) reagents. The reaction conditions and choice of oxidizing agent can influence the extent of oxidation and the final product obtained.
