Explanation

To analyze the statements provided in the question, we will evaluate each statement regarding acetaldehyde and its reactions with various tests for carbonyl compounds.

### Step 1: Evaluate Statement 1
**Statement 1:** Acetaldehyde responds positively with all the tests of carbonyl compounds like Tollen's Test, Fehling's Test, 2,4-DNP test, as well as Iodoform test.

- **Tollen's Test:** Acetaldehyde (CH3CHO) is an aldehyde and will give a positive result with Tollen's reagent (ammoniacal silver nitrate), producing a silver mirror.

- **Fehling's Test:** Acetaldehyde will also give a positive result with Fehling's solution, resulting in the formation of a red precipitate of cuprous oxide (Cu2O).

- **2,4-DNP Test:** Acetaldehyde reacts with 2,4-dinitrophenylhydrazine (2,4-DNP) to form a yellow, orange, or red precipitate, indicating a positive result.

- **Iodoform Test:** Acetaldehyde gives a positive result in the Iodoform test, as it contains the methyl group adjacent to the carbonyl group.

**Conclusion for Statement 1:** True. Acetaldehyde responds positively to all the mentioned tests.

### Step 2: Evaluate Statement 2
**Statement 2:** All aldehydes respond to all the four tests given in assertion.

- **Iodoform Test:** Not all aldehydes give a positive Iodoform test. Only those aldehydes that have a methyl group adjacent to the carbonyl group (like acetaldehyde) will give a positive result. Other aldehydes, such as formaldehyde or benzaldehyde, do not give this test.

- **Tollen's Test:** All aldehydes do respond positively to Tollen's test.

- **Fehling's Test:** All aldehydes, except for aromatic aldehydes, respond positively to Fehling's test.

- **2,4-DNP Test:** All aldehydes will give a positive result with the 2,4-DNP test.

**Conclusion for Statement 2:** False. Not all aldehydes give a positive Iodoform test.

### Final Conclusion
- **Statement 1 is True.**
- **Statement 2 is False.**

### Summary of the Solution
- **Statement 1:** True (Acetaldehyde gives positive results for all tests).
- **Statement 2:** False (Not all aldehydes give positive results for the Iodoform test).
