In the Victor Meyer's test, the colours given by `1^(@), 2^(@)` and `3^(@)` alcohols are respectively `:`

Options

A. Red,colourless , blue
B. Red,blue, colourless
C. Colourless, red , blue
D. Red blue, violet

Answer

To solve the question regarding the colors produced by primary, secondary, and tertiary alcohols in the Victor Meyer's test, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Victor Meyer's Test**:
- The Victor Meyer's test is a qualitative analysis method used to differentiate between primary, secondary, and tertiary alcohols based on the colors produced during the reaction.

2. **Procedure of the Test**:
- The alcohol sample is first treated with iodine in the presence of red phosphorus. This step converts the alcohol into an iodine alkane.
- The iodine alkane is then treated with alcoholic silver nitrate, resulting in the formation of nitroalkane.
- The nitroalkane is subsequently treated with nitrous acid (HNO2), and the resulting solution is made alkaline by adding caustic soda (NaOH).

3. **Observation of Colors**:
- After performing the above steps, the resulting solution's color is observed:
- **Primary Alcohols**: Produce a **blood red** color.
- **Secondary Alcohols**: Produce a **blue** color.
- **Tertiary Alcohols**: Produce a **colorless** solution.

4. **Conclusion**:
- Therefore, the colors observed for primary, secondary, and tertiary alcohols in the Victor Meyer's test are:
- Primary alcohol: Blood red
- Secondary alcohol: Blue
- Tertiary alcohol: Colorless

5. **Final Answer**:
- The correct option that matches these observations is **Option B: Red, Blue, Colorless**.
