in water, hydrogen bonding occurs between the hydrogen atom in one molecule and
question options:

a) an oxygen atom in the same molecule.

b) an oxygen atom in a different molecule.

c) a hydrogen atom in the same molecule.

d) a hydrogen atom in a different molecule.

e) none of the above

B) an oxygen atom in a different molecule.

Explanation:

Hydrogen bonding (H-bonding) is an inter molecular force having partial ionic-covalent character.

H-bonding takes place between a hydrogen atom attached with an electronegative atom such as O, N and F and an electronegative atom such as O,N and F. They are strong forces.

Example: has hydrogen bonding between hydrogen of one molecule with oxygen atom bonded to hydrogen of different molecule.

Thus the correct option is hydrogen bonding occurs between the hydrogen atom in one molecule and an oxygen atom in a different molecule.

yes it is balanced

beta decay is the answer
