Why is water so effective at hydrogen bonding?

Choose 1 answer:

(Choice A)

Oxygen is very electronegative and strongly attracts hydrogen's electron.

(Choice B)

Hydrogen is more electronegative than oxygen, so it is more likely to donate its electrons to oxygen.

(Choice C)

There are two hydrogens, doubling the positive charge on the water molecule.

(Choice D)

The hydrogens in water are ionically bonded to the oxygen.

Andrea Cain · Answer 1

A

Explanation:

Oxygen is one of the most electronegative element of the periodic table hence it attracts the shared pair between H and O so much that oxygen gets partial - ve charge while hydrogen gets partial + be charge. Now hydrogen becomes highly electron deficient hence it links to the line pair of any oxygen element of the the adjacent water molecules to adjust it's deficiency.

Clover · Answer 2

so A i think is the best answer

Explanation:

Because the water molecules are small, many of them can surround one molecule of the solute and form hydrogen bonds. Because of the attraction, the water molecules can pull the solute molecules apart so that the solute dissolves in the water.
