(4) Aldehyde show reducing properties duet ot their ready conversion into ketons.

Options

A. 1
B. 2
C. 3
D. 4

Answer

To determine which of the statements are correct, let's analyze each statement one by one.

**Statement 1:** To prepare ethanol, `CH₃MgI` is treated with the other reagent HCHO.

- **Analysis:** `CH₃MgI` is a Grignard reagent. When it reacts with formaldehyde (HCHO), it forms a primary alcohol after hydrolysis. The reaction can be summarized as follows:
1. `CH₃MgI` attacks the carbon of formaldehyde, forming an intermediate.
2. Upon hydrolysis, this intermediate yields ethanol (C₂H₅OH).

Therefore, this statement is **correct**.

---

**Statement 2:** Urotropine is formed by the action of HCHO with `NH₃`.

- **Analysis:** Urotropine, also known as hexamethylenetetramine, is indeed formed when formaldehyde (HCHO) reacts with ammonia (NH₃). The reaction involves multiple moles of formaldehyde and ammonia, leading to the formation of urotropine.

Thus, this statement is **correct**.

---

**Statement 3:** The conversion of acid chlorides into aldehydes by reduction is termed Rosenmund's reduction.

- **Analysis:** Rosenmund's reduction is a well-known reaction where acid chlorides are reduced to aldehydes using hydrogen gas in the presence of a palladium catalyst. This statement accurately describes the process.

Therefore, this statement is **correct**.

---

**Statement 4:** Aldehydes show reducing properties due to their ready conversion into ketones.

- **Analysis:** This statement is misleading. Aldehydes are indeed reducing agents, but they are more readily oxidized to carboxylic acids rather than converting to ketones. The reducing properties of aldehydes stem from their ability to be oxidized, not from converting into ketones.

Hence, this statement is **incorrect**.

---

**Final Conclusion:**
- The correct statements are **1, 2, and 3**. Therefore, the total number of correct statements is **3**.
