Question

16. A molecule H-X will be 50% ionic if electronegativity difference of H and X is (a) 1.2 eV (b) 1.4 eV (c) 1.5 eV (d) 1.7 eV ​

Answer 1

Answer:

d) 1.7eV

Explanation:

Pauling considered that the partial ionic character of a bond is an approximate function of the difference in electronegativity between the two bonded atoms. He estimated that a difference of 1.7 corresponds to 50% ionic character, so that a greater difference corresponds to a bond which is predominantly ionic.
