The partial negative charge at one end of a water molecule is attracted to the partial positive charge of another water molecule. This attraction is called:
A. A covalent bond
B. a hydrogen bond
C. an ionic bond

             Hydrogen Bond

Explanation:

                   Hydrogen bond interactions are formed between the hydrogen atom bonded to most electronegative atoms (i.e. F, O and N) of one molecule and most electronegative atom (i.e. F, O and N) of another molecule.

In this interaction the hydrogen atom has partial positive charge and electronegative atom has partial negative charge.

the answer would be a
