Answer: The correct answer is Option 3.
Explanation:
Electrolyte is defined as a substance which dissociates into its ions in a solution and has a capacity to conduct electricity.
From the given options:
Option 1: \(CH_3OCH_3\)
This compound belongs to ether group and it does not form ions when present in a solution. Thus, it is not considered as an electrolyte.
Option 2: \(CH_3OH\)
This compound is an alcohol and it dissociates into its ion but the ions formed are not stable. Hence, it is not considered as an electrolyte.
Option 3: \(CH_3COOH\)
This compound is a carboxylic acid and it dissociates into its ion. The ions formed or the conjugate base formed are stable. Hence, it is considered as an electrolyte.
\(CH_3COOH\rightarrow CH_3COO^-+H^+\)
Option 4: \(C_2H_5CHO\)
This compound is an aldehyde and it does not form ions when present in a solution. Thus, it is not considered as an electrolyte.
From the above information, the correct answer is Option 3.
