Question

List the following compounds in decreasing electronegativity difference.

Answer 1

Answer:

Based on Pauling Scale, electro negativity of Cl = 3.2, Na = 0.9 and H = 2.1

Explanation:

Thus, Electronegativity difference  in Cl2 = 3.2 -3.2 = 0

Electronegativity difference  in NaCl = 3.2-0.9 = 2.3

Similarly, Electronegativity difference  in HCl = 3.2 - 2.1 = 1.1

Thus, among the listed molecules following is the decreasing order of electronegativity difference: NaCl> HCl > Cl2
