Correct order of electronegativity of `N,P,C` and `Si` on Pauling scale is:

Options

A. `N gt P gt C gt Si`
B. `C gt Si gt N gt P`
C. `N lt P lt C lt Si`
D. `N gt C gt P gt Si`

Explanation

To determine the correct order of electronegativity of Nitrogen (N), Phosphorus (P), Carbon (C), and Silicon (Si) on the Pauling scale, we can follow these steps:

### Step 1: Understand Electronegativity Trends
Electronegativity is the tendency of an atom to attract electrons in a chemical bond. The general trends in the periodic table are:
- Electronegativity increases across a period (from left to right).
- Electronegativity decreases down a group (from top to bottom).

**Hint:** Remember that elements on the right side of the periodic table are more electronegative than those on the left.

### Step 2: Identify the Position of Elements
- Nitrogen (N) is in Group 15 and Period 2.
- Carbon (C) is in Group 14 and Period 2.
- Phosphorus (P) is in Group 15 and Period 3.
- Silicon (Si) is in Group 14 and Period 3.

**Hint:** Look at the groups and periods of the elements to understand their relative positions.

### Step 3: Assign Electronegativity Values
According to the Pauling scale, the electronegativity values for these elements are:
- Nitrogen (N): 3.0
- Carbon (C): 2.5
- Phosphorus (P): 2.1
- Silicon (Si): 1.8

**Hint:** Memorize the electronegativity values or refer to a periodic table that includes these values.

### Step 4: Compare the Values
Now, we can compare the electronegativity values:
- Nitrogen (3.0) > Carbon (2.5) > Phosphorus (2.1) > Silicon (1.8)

**Hint:** Arrange the values from highest to lowest to find the correct order.

### Step 5: Write the Correct Order
From the comparison, the correct order of electronegativity from highest to lowest is:
1. Nitrogen (N)
2. Carbon (C)
3. Phosphorus (P)
4. Silicon (Si)

Thus, the correct order of electronegativity of N, P, C, and Si on the Pauling scale is:
**N > C > P > Si**

**Final Answer:** The correct order of electronegativity is N > C > P > Si.
