Assertion : When the vapours of a primary, secondary or tertiary alcohol are passed over heated copper at 573 K, an aldehyde or ketone is formed. Reason : Reduction of alcohols takes place

Options

A. if both assertioon and reason are true and reason is the corrct explanation of assertion.
B. If both assertion and reason are ture but reason is not the corrcet explanation of assertion.
C. If assertion is true but reason is false .
D. if both assertion and reason are false.

Explanation

To solve the question regarding the assertion and reason statements about the behavior of alcohols when passed over heated copper, we will analyze both statements step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that when the vapors of primary, secondary, or tertiary alcohols are passed over heated copper at 573 K, an aldehyde or ketone is formed.
- **Analysis**:
- Primary alcohols are oxidized to aldehydes.
- Secondary alcohols are oxidized to ketones.
- Tertiary alcohols do not undergo oxidation to form aldehydes or ketones; instead, they dehydrate to form alkenes.
- **Conclusion**: The assertion is **incorrect** because it implies that all types of alcohols produce aldehydes or ketones, which is not true for tertiary alcohols.

2. **Understanding the Reason**:
- The reason states that the reduction of alcohols takes place.
- **Analysis**:
- In the context of the reaction with copper at 573 K, alcohols are actually oxidized, not reduced. Oxidation involves the removal of hydrogen (dehydrogenation).
- **Conclusion**: The reason is also **incorrect** because it misrepresents the process occurring during the reaction.

3. **Final Evaluation**:
- Since both the assertion and the reason are incorrect, we conclude that the correct answer is that both statements are false.

### Final Answer:
Both the assertion and reason are false.
