Question

The electronegativity values of $C,N,O$ and $F$ on Pauling scale:

• A. Decrease from carbon to fluorine.
• B. Increase from carbon to fluorine.
• C. Increase upto oxygen and then decrease upto fluorine.
• D. Decrease from carbon to nitrogen and then increase continyously.

Answer 1

The correct option is B Increase from carbon to fluorine.

Electronegativity is a measure of an atom's ability to attract shared electrons to itself. On the periodic table, electronegativity generally increases as you move from left to right across a period due to increase in effective nuclear charge.
Therefore, electronegativity increases from carbon to fluorine.
