AI Generated Solution
The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided.
### Step 1: Analyze the Assertion
The assertion states that "Glucose reacts with hydroxylamine to form an oxime and also adds a molecule of hydrogen cyanide to give cyanohydrin."
1. **Understanding Glucose**: Glucose is an aldehyde with the structure C6H12O6. In its open-chain form, it has a carbonyl group (C=O) at the first carbon.
2. **Reaction with Hydroxylamine**: When glucose reacts with hydroxylamine (NH2OH), it forms an oxime. This reaction involves the nucleophilic attack of hydroxylamine on the carbonyl carbon of glucose, leading to the formation of an oxime and the elimination of a water molecule.
3. **Reaction with Hydrogen Cyanide**: When glucose reacts with hydrogen cyanide (HCN), the carbonyl carbon is attacked by the cyanide ion (CN-), resulting in the formation of a cyanohydrin. This reaction also involves the addition of a hydrogen ion (H+) to the oxygen atom of the carbonyl group.
### Conclusion for Assertion
Both parts of the assertion are correct: glucose does react with hydroxylamine to form an oxime and with hydrogen cyanide to form a cyanohydrin.
### Step 2: Analyze the Reason
The reason states that "The carbonyl group is present in the open chain structure of glucose."
1. **Carbonyl Group in Glucose**: In the open-chain form of glucose, there is indeed a carbonyl group (aldehyde) at the first carbon. This is crucial for the reactions mentioned in the assertion.
2. **Link to the Assertion**: The presence of the carbonyl group is what allows glucose to react with both hydroxylamine and hydrogen cyanide, leading to the formation of oximes and cyanohydrins.
### Conclusion for Reason
The reason is also correct because the carbonyl group in glucose's open-chain structure is what enables the reactions described in the assertion.
### Final Conclusion
Since both the assertion and reason are correct, and the reason correctly explains the assertion, the correct answer is:
**(a) Both assertion and reason are correct statements, and reason is the correct explanation of the assertion.**
