(A)Glycerol does not react with HI.
(R ) 2-Iodopropane can be produce by treatment of glycerol with HI.

Options

A. If both (A) and (R ) are correct and (R ) is correct explanation of (A ).
B. If both (A ) and (R ) are correct but (R ) is not correct explanation of (A ).
C. If (A) is correct but (R ) is incorrect
D. If (A) is incorrect but (R ) is correct.

Answer

To analyze the statements given in the question, we will break down the reasoning step by step.

### Step 1: Understand the Structure of Glycerol
Glycerol, also known as glycerin, has the chemical formula C3H8O3. Its structure consists of three carbon atoms, each bonded to a hydroxyl (–OH) group. The structure can be represented as follows:

```
H H H
| | |
H–C–C–C–OH
| | |
OH OH OH
```

### Step 2: Analyze Statement (A)
Statement (A) claims that glycerol does not react with HI (hydroiodic acid). To evaluate this, we need to consider the reactivity of glycerol with HI.

### Step 3: Reaction of Glycerol with HI
When glycerol reacts with HI, the hydroxyl groups (–OH) can be protonated by the hydrogen ion (H+), forming a good leaving group (H2O). The reaction proceeds as follows:

1. Protonation of the hydroxyl group:
```
C3H8O3 + HI → C3H8OH2+ + I−
```

2. The protonated hydroxyl group (H2O) leaves, allowing the iodide ion (I−) to attack the carbon atoms.

### Step 4: Formation of 2-Iodopropane
As the reaction continues, the iodide ion can attack the carbon atoms, leading to the formation of 2-iodopropane (C3H7I). The reaction can be summarized as:
```
C3H8O3 + HI → C3H7I + H2O
```
This indicates that 2-iodopropane can indeed be produced from glycerol when treated with HI.

### Step 5: Analyze Statement (R)
Statement (R) claims that 2-iodopropane can be produced by the treatment of glycerol with HI. Based on the reaction we analyzed, this statement is correct.

### Conclusion
- Statement (A) is **incorrect** because glycerol does react with HI.
- Statement (R) is **correct** because 2-iodopropane is produced from glycerol when treated with HI.

### Final Answer
The correct option is **D**: A is incorrect, but R is correct.
