Which of the following statements are true about hydrogen bonds? (More than one) A.) A hydrogen bond is stronger than a covelent bond.
B.) They are the strongest bonds that form between molecules.
C.) The attraction between the hydrogen atom on one water molecule and the oxygen atom on
another water molecule is an example,
D.) A hydrogen bond is stronger than an ionice bond.

B.) They are the strongest bonds that form between molecules.

C.) The attraction between the hydrogen atom on one water molecule and the oxygen atom on  another water molecule is an example,

Hydrogen bonds exists between molecules in which hydrogen is bonded to a high electronegative atom such as nitrogen, chlorine, fluorine, sulphur etc.

Hydrogen bonds are strong intermolecular interactions. They are responsible for the high boiling and melting points of some polar substances such as water.

However, hydrogen bonds are not as strong as covalent or ionic bonds.

B,C

Explanation: covalent and ionic bonds hold molecules together. It is the polarity of covalent bonds that give rise to hydrogen bonding. As in the water example: the more electronegative O attracts electrons slightly more than the hydrogens, so the O has a fractional negative charge, the Hs a slight positive charge. The O of one molecule and the H of another are held together by this charge difference.
