Question 5
Hydrogen bonds form due to the attraction between a partially positive hydrogen atom (in a polar covalent bond) and a partially negative atom (like O, N, F) in another molecule. The principle "Opposites Attract" (positive and negative charges attracting) explains this attraction. The other options are incorrect: "Opposites Repel" is the opposite of what happens, "Hydrogens Float" is irrelevant, and "Gorilla glue" is a non - scientific distractor.
In a water molecule ($H_2O$), the oxygen atom is more electronegative than hydrogen. This means oxygen pulls the shared electrons in the covalent bonds closer to itself. As a result, the area near the oxygen atom has a partial negative charge, while the hydrogen atoms have partial positive charges. Carbon is not part of a water molecule.
Water is a polar molecule because of the unequal sharing of electrons between oxygen and hydrogen atoms. Oxygen is more electronegative, so it pulls the electrons in the O - H bonds closer to itself. This creates a partial negative charge near oxygen and partial positive charges near hydrogen. Ionic bonding involves the transfer of electrons (not sharing), transfer of electrons is characteristic of ionic bonds (not covalent in water), and equal sharing of electrons would result in a non - polar molecule (like in $O_2$ or $H_2$).
