Hydrogen bond is a type of intermolecular force, a strong bond that is formed due to a dipole-dipole attraction, and it will occur when Hydrogen atom bonds with strongly electronegative atoms, like F, O or N. According to this explanation, let's analyze the options:
A) Hydrogen bond will not occur between two hydrogen atoms, because there is no dipole being formed between them
B) It is not a covalent bond, since it is an interaction between molecules and not atoms, and another reason is that H bonds are strong in terms of dipoles, and covalent bondings will not have that electronegative difference
C) Water is a polar molecule, and that would be a reason for why we have hydrogen bonds
D) Since hydrogen bonds are based on a strong difference in electronegativity, it is considered to be a strong interaction
E) As I wrote in the explanation, yes this interaction between H and O will represent a hydrogen bond
F) Yes! When we talk about hydrogen bonds, we are talking about interaction between molecules and not atoms
Correct:
C
E
F
