A : Formaldehyde undergoes Cannizzaro reaction in the presence of `H^(+)`.
R : Formaldehyde has two `alpha`-Hydrogen atoms.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1).
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2).
C. If Assertion is true statement but Reason is false, then mark (3).
D. If both Assertion and Reason are false statements, then mark (4).

Answer

To solve the question, we need to analyze the statements given:

**Statement A:** Formaldehyde undergoes Cannizzaro reaction in the presence of `H^(+)`.
**Statement R:** Formaldehyde has two `alpha`-Hydrogen atoms.

### Step 1: Understanding the Cannizzaro Reaction
The Cannizzaro reaction is a redox reaction that occurs with aldehydes lacking alpha-hydrogens when treated with a strong base (like NaOH) or sometimes in acidic conditions. In this reaction, one molecule of aldehyde is oxidized to a carboxylic acid, while another molecule is reduced to an alcohol.

### Step 2: Analyzing Formaldehyde
Formaldehyde (HCHO) is the simplest aldehyde. Its structure can be represented as:
```
H
|
C = O
|
H
```
In this structure, we can see that formaldehyde has no alpha-hydrogens because it has only one carbon atom and thus no adjacent carbon atoms that could provide alpha-hydrogens.

### Step 3: Evaluating Statement A
Since formaldehyde does not have any alpha-hydrogens, it can indeed undergo the Cannizzaro reaction, but it typically requires a basic medium (not acidic). Therefore, the statement that formaldehyde undergoes the Cannizzaro reaction in the presence of `H^(+)` is incorrect.

### Step 4: Evaluating Statement R
Statement R claims that formaldehyde has two alpha-hydrogens. As we established earlier, formaldehyde does not have any alpha-hydrogens. Therefore, this statement is also incorrect.

### Conclusion
Both statements A and R are false. Therefore, the correct conclusion is that both statements are incorrect.

### Final Answer
Both statements A and R are false.
