Options

A.
B.
C.
D. Both A and C

Answer

To solve the problem of determining the product obtained from the reaction of cyclobutyl amine with HNO2 followed by treatment with water, we can follow these steps:

### Step 1: Identify the Reactant
The reactant is cyclobutyl amine, which has the structure:
```
NH2
|
C-C
| |
C-C
```
This is a cyclic amine with the amine group (-NH2) attached to a cyclobutane ring.

### Step 2: Reaction with HNO2
When cyclobutyl amine reacts with nitrous acid (HNO2), it undergoes a diazotization reaction. The amine group (-NH2) is converted into a diazonium salt. The general reaction can be represented as:
```
R-NH2 + HNO2 → R-N2^+ + H2O
```
In this case, R is the cyclobutyl group. Therefore, we form cyclobutyl diazonium salt:
```
N≡N^+
|
C-C
| |
C-C
```

### Step 3: Treatment with Water
The diazonium salt is unstable and will decompose when treated with water. The nitrogen gas (N2) is released, and the diazonium group is replaced by a hydroxyl group (-OH), leading to the formation of cyclobutanol:
```
R-N2^+ + H2O → R-OH + N2↑
```
Thus, we have:
```
OH
|
C-C
| |
C-C
```
This structure represents cyclobutanol.

### Conclusion
The final product obtained from the reaction of cyclobutyl amine with HNO2 followed by treatment with water is cyclobutanol.

### Final Answer
The possible product is cyclobutanol.
