Which of the following is a false statement

Options

A. Fluorine is more electronegative than chlorine
B. Nitrogen has greater `IE_(1)` than oxygen
C. Lithium is amphoteric
D. Chlorine is an oxidising agent

Explanation

To determine which of the statements is false, we will analyze each statement one by one.

### Step 1: Analyze the first statement
**Statement:** Fluorine is more electronegative than chlorine.
**Analysis:** This statement is true. Fluorine is indeed the most electronegative element in the periodic table, with a higher electronegativity value than chlorine.

### Step 2: Analyze the second statement
**Statement:** Nitrogen has greater anionic acid than oxygen.
**Analysis:** This statement is also true. Nitrogen, with its half-filled p-orbital configuration (1s² 2s² 2p³), is more stable and requires more energy to remove an electron compared to oxygen (1s² 2s² 2p⁴), which has a partially filled configuration. Thus, nitrogen has a higher anionic acid energy.

### Step 3: Analyze the third statement
**Statement:** Lithium is an amphoteric.
**Analysis:** This statement is false. Lithium is an alkali metal and primarily exhibits basic properties, not amphoteric behavior. Amphoteric substances can act as both acids and bases, which is not characteristic of lithium.

### Step 4: Analyze the fourth statement
**Statement:** Chlorine is an oxidizing agent.
**Analysis:** This statement is true. Chlorine is known to act as an oxidizing agent because it can gain electrons from other substances, thereby oxidizing them.

### Conclusion
The false statement among the options provided is: **"Lithium is an amphoteric."**
