Which statement accurately describes a hydrogen bond as presented in the text?

  • A: It's a strong covalent bond between hydrogen and carbon.
  • B: It involves a partial positive charge on a hydrogen atom attracted to a partial negative charge on another electronegative atom like oxygen or nitrogen.
  • C: It's an attraction that only occurs between nonpolar molecules.
  • D: It results in a complete transfer of electrons between atoms.

Explanation

The text states that a hydrogen bond is a noncovalent attraction between a hydrogen atom with a partial positive charge and a different electronegative atom usually oxygen or nitrogen with a partial negative charge. This aligns perfectly with option B.
