Explanation:
In the given-question, the attachment file, which is "graph" is missing. so, in this question, firstly we add the file and then provide the solution:
please find the attachment of the image file.
Solution:
In the given graph by canceling, the out ends for getting the middle median that is equal to 2, that's why its value is equal to "9".
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
