JEE Main Chemistry question

For the formation of a (predominantly) covalent bond, the difference in electronegativity values should be:

(A)Equal to or less than 1.7Correct
(B)More than 1.7
(C)1.7 or more
(D)None of the above

Answer: (A)

Solution

By convention (based on Pauling's percent-ionic-character scale), an electronegativity difference of exactly 1.7 corresponds to about 50% ionic and 50% covalent character. A
