C. X-n-hexanol , Y-Saccharic acid
D. X-n-hexane , Y-Saccharic acid

Answer

To solve the question `X overset(HI)larr "Glucose" overset(HNO_3)to Y`, we need to identify the compounds X and Y based on the reactions of glucose with HI (hydriodic acid) and HNO3 (nitric acid).

### Step-by-Step Solution:

1. **Identify the structure of Glucose**:
- Glucose is an aldohexose with the molecular formula C6H12O6. Its structure features an aldehyde group (-CHO) at one end and multiple hydroxyl groups (-OH) along the carbon chain.

2. **Reaction of Glucose with HNO3**:
- When glucose is treated with nitric acid (HNO3), it undergoes oxidation. The aldehyde group and the hydroxyl groups are oxidized to carboxylic acid groups.
- The product formed from this reaction is D-Glucaric Acid (also known as Saccharic Acid), which has the formula C6H10O8.

3. **Identify Y**:
- From the oxidation of glucose with HNO3, we conclude that Y = D-Glucaric Acid (Saccharic Acid).

4. **Reaction of Glucose with HI**:
- When glucose reacts with hydriodic acid (HI), it undergoes reduction. The aldehyde and hydroxyl groups are reduced to form an alkane.
- The product of this reaction is n-hexane (C6H14), which is a straight-chain alkane.

5. **Identify X**:
- From the reduction of glucose with HI, we conclude that X = n-Hexane.

### Final Answer:
- X = n-Hexane
- Y = D-Glucaric Acid (Saccharic Acid)
