Question

The correct order of electronegativity values of the following elements is

• A. C<N<F<O
• B. C<O<N<F
• C. C<N<O< F
• D. N<C<O<F

Answer 1

The Correct Option is C

Step 1: Recall the trend of electronegativity in the periodic table.

Electronegativity increases across a period (left to right) and decreases down a group (top to bottom). This means that within the second period, the electronegativity increases as we move from \( C \) to \( F \).

Step 2: Arrange the elements based on their positions in the periodic table.

• \( C \): Group 14, Period 2
• \( N \): Group 15, Period 2
• \( O \): Group 16, Period 2
• \( F \): Group 17, Period 2

Since electronegativity increases from left to right, the correct order is:

\[ C < N < O < F. \]

Final Answer: The correct order of electronegativity is \( \mathbf{C < N < O < F} \), which corresponds to option \( \mathbf{(3)} \).
