Mark the correct statement

Options

A. Methyl amine is slightly acidic
B. Methyl amine is less basic than ammonia
C. Methyl amine is a stronger base than `NH_(3)`
D. Methyl amine forms salts with alkalies

Explanation

To solve the question, we need to analyze each statement regarding methyl amine (CH3NH2) and determine which one is correct. Let's break it down step by step.

### Step 1: Analyze the first statement
**Statement:** Methyl amine is slightly acidic.

**Analysis:** Methyl amine (CH3NH2) is not acidic; it is basic. The presence of the nitrogen atom with a lone pair of electrons allows it to accept protons (H+), which is characteristic of bases. Therefore, this statement is incorrect.

### Step 2: Analyze the second statement
**Statement:** Methyl amine is less basic than ammonia.

**Analysis:** Ammonia (NH3) has a lone pair of electrons on the nitrogen, which can accept protons. However, methyl amine has a methyl group (CH3) that donates electron density to the nitrogen through the +I (inductive) effect, making methyl amine more basic than ammonia. Thus, this statement is also incorrect.

### Step 3: Analyze the third statement
**Statement:** Methyl amine is a stronger base than NH3.

**Analysis:** As established, the methyl group in methyl amine increases the electron density on the nitrogen atom, enhancing its ability to accept protons. This makes methyl amine a stronger base compared to ammonia. Therefore, this statement is correct.

### Step 4: Analyze the fourth statement
**Statement:** Methyl amine forms salt with alkenes.

**Analysis:** Alkenes are hydrocarbons that do not readily react with amines to form salts. They are fully hybridized and do not have the necessary reactivity to interact with the lone pair on the nitrogen of methyl amine. Therefore, this statement is incorrect.

### Conclusion
After analyzing all the statements, the only correct statement is that **methyl amine is stronger than ammonia (NH3)**.

### Final Answer
The correct statement is: **Methyl amine is stronger base than NH3.**
