C) H2O has the strongest dipole interactions
Explanation:
The dipole interactions are the interactions that occur between polar molecules.
Polar molecules form when the atoms forming the molecule have different electronegativity, therefore one of the atom in the molecule attract the shared electrons more towards itself; as a result, the molecule ends up having a region which is slightly negatively charged and a region slightly positively charged.
In this problem, we are comparing 4 different molecules. We observe that:
H2: this molecule is formed by 2 atoms of hydrogen - since the two atoms are identical, electrons are equally shared between the two atoms, so this molecule is not polar
O2: this molecule is formed by 2 identical atoms of oxygen, so it is not polar, for the same reason as H2
CH4: this molecule consists of a carbon atom surrounded by 4 hydrogen atoms - since this molecule has a symmetric structure, the charge is balanced, therefore this molecule is not polar
H2O (water): the oxygen atom in the water molecule is more electronegative than the hydrogens, therefore it tends to attract more the shared electrons - as a result, the molecule is polar.
Therefore, the correct answer is H2O.

Answer: m Most likely Group2 metals and Group 17 non-ktta
Explanation:
A little more information is needed to be certain, but the likely answer is that X belongs to Group 2 and Y belongs to Group 17. Group 2 metals (Be, Mg, Ca, Sr, Ba, etc.) are all divalent. They gave rive up 2 electrons each to return to a full shell. Group 17 elements (e,g, F, Cl, Br, I, etc.) all require 1 electron to reach a full valence shell. That would make the proportion 1X to 2Y, or XY2. It is possible that a metal outside of Group 2 would also have a valency of 2. Iron(II) forms FeCl2, for example.
