Answer: Option (A) is the correct answer.
Explanation:
Polarity in a substance or molecules arises when the two combining atoms have different electronegativites. As more electronegative atom will attract the electrons from electropositive atom towards itself.
Due to this there will development of partial positive charge on electropositive atom and a partial negative charge on the electronegative atom.
For example, in water ([tex]H_{2}O[/tex]) due to the difference in electronegativities of hydrogen and oxygen atoms there is partial positive charge on hydrogen atom and partial negative charge on oxygen atom.
Due to these charges it is able to attract ions of opposite charge that are surrounding.
Thus, we can conclude that one of the most important characteristics of the water molecule is its polarity, which allows it to surround and attract both positive and negative ions.
One of the most important characteristics of the water molecule is its polarity, which allows it to surround and attract both positive and negative ions.
Further Explanation:
Polarity of a water molecule
- A water molecule is polar because the electric charge is distributed unevenly because the oxygen atom is on one end, causing it to have a slight negative and a slight positive charge.
- The polarity of water makes to be a good solvent since it allows it to dissolve both ionic bonds and other polar molecules.
- The polar nature of water gives each of its molecule a hydrophobic side and a hydrophillic end. each molecule of water has two hydrogen atoms that are partially positive an an atom of oxygen that carries a partial negative charge.
- Water polarization allows it to attract many different types of molecules such as ionic compounds and salts.
Hydrogen bonding in water
- Hydrogen bond is a type of bond that occurs between a hydrogen atom and a more electronegative atom such as oxygen and nitrogen.
- In water for example; hydrogen atoms in a molecule of water have a partial positive charge while the oxygen atom has a partial negative charge.
- This results to the formation of hydrogen bonds in molecules of water between partial positive hydrogen atom in one molecule and partial negative oxygen in another molecule.
- Hydrogen bonding is responsible for the polarity in water molecules.
