determine whether each pair of chemicals could be separated by an acid or base extraction.

determine whether each pair of chemicals could be separated by an acid or base extraction.
Answer
Explanation:
Step1: Analyze first - pair
Toluene ($C_6H_5CH_3$) is non - polar and aniline ($C_6H_5NH_2$) is basic. Aniline can react with an acid to form a water - soluble salt. So, they can be separated by an acid extraction.
Step2: Analyze second - pair
Both benzoic acid ($C_6H_5COOH$) and 2 - phenylacetic acid ($C_6H_5CH_2COOH$) are carboxylic acids. They both react with bases in a similar way. So, they cannot be separated by acid or base extraction.
Step3: Analyze third - pair
Toluene ($C_6H_5CH_3$) is non - polar and benzaldehyde ($C_6H_5CHO$) is a neutral compound. Neither of them has acidic or basic properties that would allow separation by acid or base extraction. So, they cannot be separated by acid or base extraction.
Answer:
- Can be separated by an acid extraction
- Cannot be separated by acid or base extraction
- Cannot be separated by acid or base extraction
