Question

which statement about hydrogen bonds and covalent bonds is true?
covalent bonds occur when the partial negative charge of one molecule is attracted to a partial positive charge of a different molecule.
covalent bonds occur between atoms in the same molecule while hydrogen bonds between atoms of different molecules.
hydrogen bonds are stronger than covalent bonds when they occur between water molecules.
both covalent and hydrogen bonds share electrons equally between atoms.

Explanation:

Covalent bonds are intramolecular, formed by sharing electrons between atoms in the same molecule. Hydrogen bonds are intermolecular, formed between a hydrogen - bonded to a highly electronegative atom in one molecule and an electronegative atom in another molecule.

Answer:

Covalent bonds occur between atoms in the same molecule while hydrogen bonds between atoms of different molecules.
