<u>Answer:</u> The order of intermolecular forces among the given compounds will be:
<u>Explanation:</u>
Electronegativity is defined as the property of the element to attract the shared pair of electrons towards itself.
Strongest intermolecular forces of attraction means that the electronegativity difference between the elements forming bond is more, more polar is the bond.
Electronegativities of the elements are:
Hydrogen: 2.1
Fluorine: 3.98
Chlorine: 3.16
Bromine: 2.96
Iodine: 2.66
Electronegativity difference in HF = 3.98 - 2.1 = 1.88
Electronegativity difference in HCl = 3.16 - 2.1 = 1.06
Electronegativity difference in HBr = 2.96 - 2.1 = 0.86
Electronegativity difference in HI = 2.66 - 2.1 = 0.56
As, the electronegativity difference of Hf is the highest, so it has the strongest intermolecular forces of attraction.
Hence, the order of intermolecular forces among the given compounds will be:

Answer:
Cu
Explanation:
We can use oxidation numbers to figure out what is happening with the electrons.
The oxidation number of Cu increases from 0 to +2 in Cu(NO₃)₂. The copper has gained two positive charges, so it has lost two electrons. It has been oxidized, so it is the reducing agent.
NO₃⁻ is wrong. The oxidation number of N decreases from +5 in NO₃⁻ to +4 in NO₂, so it has been reduced. It is the oxidizing agent.
Cu(NO₃)₂ and NO₂ are wrong. They are the products of the reaction. They cannot be either oxidizing or reducing agents in this reaction
