Question

checkpoint: hydrogen bonds 1
how are hydrogen bonds different from covalent and ionic bonds?
select the best answer:
hydrogen bonds dont involve electrons being shared or transferred.
hydrogen bonds occur within atoms.
hydrogen bonds are stronger than all other bonds.
hydrogen bonds only happen with water.
hydrogen bonds arent different from covalent and ionic bonds.

Explanation:

• Covalent bonds involve sharing electrons, ionic bonds involve transferring electrons.
• Hydrogen bonds are intermolecular forces (between molecules), not true bonds like covalent (intramolecular - within a molecule, sharing electrons) or ionic (intramolecular - transfer of electrons).
• Hydrogen bonds don't involve electron sharing or transfer.
• Hydrogen bonds occur between molecules (not within atoms as in covalent/ionic which are within molecules).
• Hydrogen bonds are weaker than covalent and ionic bonds.
• Hydrogen bonds occur in many substances (not just water, e.g., in DNA base - pairing).

Answer:

Hydrogen bonds don't involve electrons being shared or transferred.
