Ceric ammonium nitrate and `CHCl_(3)` / alc. KOH are used for the identification of functional groups present in ______ and ______ respectively.

Options

A. Alcohol, phenol
B. Amine, alcohol
C. Alcohol, amine
D. Amine, phenol

Answer

To solve the question regarding the identification of functional groups present in compounds using ceric ammonium nitrate and chloroform/alc. KOH, we can break it down into steps.

### Step-by-Step Solution:

1. **Understanding Ceric Ammonium Nitrate (CAN)**:
- Ceric ammonium nitrate is a reagent commonly used to identify alcohols. When alcohols react with ceric ammonium nitrate, they form a complex that results in a color change, typically producing a red or pink precipitate.

2. **Identifying the Functional Group for Ceric Ammonium Nitrate**:
- The positive test with ceric ammonium nitrate indicates the presence of alcohol functional groups (–OH). Therefore, ceric ammonium nitrate is used for the identification of **alcohols**.

3. **Understanding Chloroform and Alcoholic KOH**:
- The combination of chloroform and alcoholic KOH is used in the Carbylamine test, which is a method to identify primary amines. When primary amines react with chloroform and alcoholic KOH, they produce isocyanides (or carbylamines), which have a characteristic unpleasant smell.

4. **Identifying the Functional Group for Chloroform/alc. KOH**:
- The positive test with chloroform and alcoholic KOH indicates the presence of amine functional groups (–NH2). Therefore, this reagent is used for the identification of **amines**.

5. **Final Conclusion**:
- Based on the above analysis, ceric ammonium nitrate is used for the identification of **alcohols**, and chloroform/alcoholic KOH is used for the identification of **amines**.

### Final Answer:
Ceric ammonium nitrate is used for the identification of **alcohols**, and chloroform/alcoholic KOH is used for the identification of **amines**.
