List the following compounds in decreasing electronegativity difference. cl2 hcl nacl

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

Thus, Electronegativity difference  in [tex] Cl_{2} [/tex] = 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 > [tex] Cl_{2} [/tex]

The decreasing order of electronegativity difference: NaCl > HCl > Cl₂

As per Pauling scale:

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

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
