Question

Which of the following statements are correct?

I) With the help of electronegativity difference between two bonded atoms, polarity of the bond can be explained

II) With increase of energy of electron in an atom, the ionisation potential value of that atom increase

III) For multivalent atoms, electronegativity can be explained with the help of Mulliken scale

IV) Highest electronegative element is fluorine

• A. I and II
• B. II and III
• C. III and IV
• D. I and IV

Answer 1

The correct option is D

I and IV

II – Higher the energy of electron in the atom, lower the energy required to remove electron away from nucleus.

III – Mulliken scale is limited to monovalent elements
