A : Ethanol undergoes haloform reaction.
R : Ethanol can be oxidised into ethanal.

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 determine the correctness of the statements A and R, we will analyze each statement step by step.

### Step 1: Analyzing Statement A
**Statement A:** Ethanol undergoes haloform reaction.

- The haloform reaction typically occurs with methyl ketones or compounds that can be oxidized to methyl ketones. Ethanol (C2H5OH) can be oxidized to ethanal (acetaldehyde, CH3CHO), which is a necessary precursor for the haloform reaction.
- In the presence of halogens (like iodine, I2) and a base (like sodium hydroxide, NaOH), ethanol can be converted to the corresponding haloform (in this case, iodoform, CHI3) through a series of reactions.

### Step 2: Analyzing Statement R
**Statement R:** Ethanol can be oxidized into ethanal.

- Ethanol can indeed be oxidized to ethanal. This can be done using mild oxidizing agents such as PCC (Pyridinium chlorochromate) or even with stronger oxidizing agents under controlled conditions.
- The oxidation process involves the conversion of the hydroxyl group (-OH) in ethanol to a carbonyl group (C=O) in ethanal.

### Conclusion
Both statements A and R are correct:
- Ethanol undergoes the haloform reaction after being oxidized to ethanal.
- Ethanol can be oxidized to ethanal.

### Final Answer
Both A and R are true.
