Question

Arrange the following elements in order of increasing electronegative Cl, C, O,F N

Answer 1

Answer:

C<Cl<O<F

Explanation:

• Electronegativity of a bonded atom decreases with increase in size so the forces of attractions on valence shell electrons decrease and hence Electronegativity decreases.
• When effective nuclear charge is high the nucleus will attract the shared electrons with greater strength and the Electronegativity will be high.
• This effect increases the atomic size which decreases the Electronegativity value.
