Out of n-propyl alcohol and isopropyl alcohol, which will give blood red colouration in Victor Meyer's test ?

Answer

To determine which alcohol, n-propyl alcohol or isopropyl alcohol, gives a blood red coloration in Victor Meyer's test, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structures of the Alcohols**:
- n-Propyl alcohol (1-propanol) has the structure: CH3-CH2-CH2-OH (a primary alcohol).
- Isopropyl alcohol (2-propanol) has the structure: CH3-CH(OH)-CH3 (a secondary alcohol).

2. **Understand Victor Meyer's Test**:
- Victor Meyer's test is a qualitative test used to differentiate between primary, secondary, and tertiary alcohols based on their reactivity and the color of the resulting products.
- Primary alcohols give a blood red coloration, secondary alcohols give a blue coloration, and tertiary alcohols result in a colorless solution.

3. **Determine the Type of Alcohols**:
- n-Propyl alcohol is a primary alcohol.
- Isopropyl alcohol is a secondary alcohol.

4. **Predict the Outcome of the Test**:
- According to the results of Victor Meyer's test:
- n-Propyl alcohol (primary) will yield a blood red coloration.
- Isopropyl alcohol (secondary) will yield a blue coloration.

5. **Conclusion**:
- Since the question asks which alcohol gives a blood red coloration, the answer is n-propyl alcohol.

### Final Answer:
**n-Propyl alcohol will give blood red coloration in Victor Meyer's test.**
