A hydrogen bond is a(n) ____.
A) shared pair of electrons between a hydrogen and an oxygen nucleus
B) shared pair of electrons between a hydrogen nucleus and either an oxygen or a nitrogen nucleus
C) attraction between a covalently bonded hydrogen atom and another atom taking part in a separate polar covalent bond
D) attraction between an ionically bonded hydrogen atom and another atom taking part in a separate polar covalent bond
E) a strong chemical bond between two ions that are each bonded to other polar compounds
Hydrogen Bond
Attraction between a covalently bonded hydrogen atom and another atom taking part in a separate polar covalent bond.
Polar Covalent Bond
A type of chemical bond where electrons are unequally shared between atoms, leading to partial electric charges.
Covalently Bonded
Atoms that are linked together by sharing pairs of electrons to achieve stability.

Final Answer :
C
Explanation :
Hydrogen bonds are a type of dipole-dipole interaction that occurs between a hydrogen atom, which is covalently bonded to a highly electronegative atom (such as oxygen or nitrogen), and another electronegative atom bearing a lone pair of electrons. This definition matches choice C, which correctly describes a hydrogen bond as an attraction between a covalently bonded hydrogen atom and another atom involved in a separate polar covalent bond.
