The haloform reaction of acetone with sodium hypobromite yields:

• (a) - acetic acid
• (b) - propionic acid
• (c) - acetaldehyde
• (d) - isopropyl alcohol

The haloform reaction involves the reaction of a methyl ketone, like acetone, with a halogenating agent such as sodium hypobromite. In this case, acetone (which is 2-propanone) reacts to form a haloform compound and a carboxylic acid.

Products of the Reaction

When acetone undergoes this reaction, it primarily yields:

• Acetic Acid - This is the correct answer. The reaction leads to the formation of acetic acid as a byproduct.

Why Acetic Acid?

The haloform reaction specifically targets the methyl group adjacent to the carbonyl group in acetone, resulting in the cleavage of the carbon-carbon bond and the formation of acetic acid.

In summary, the haloform reaction of acetone with sodium hypobromite yields acetic acid. Therefore, the answer is (a) - acetic acid.
