Question

(A) Hydrogen bonds only.
(B) Nonpolar covalent bonds only.
(C) Ionic and nonpolar hydrogen bonds.
(D) Both polar covalent and hydrogen bonds.
(E) Metallic and ionic bonds.

Answer 1

We know that polarity, when all is said in done, alludes to the actual properties of mixes, for example, boiling point, melting points, and their solubility. The polarity of bonds basically emerges from the demonstration among particles and molecules with different electronegativities.

Complete step by step solution:
Polarity of bonds can be defined as a state or a condition of a particle or an atom having positive and furthermore negative charges, particularly if there should arise an occurrence of magnetic or an electrical pole.
Polar Molecules: A polar particle is generally formed when the one end of the atom is said to have more number of positive charges and though the far edge of the atom has negative charges, making an electrical shaft. At the point when an atom is said to have a polar bond, at that point the center of the negative charge will be one side, while the focal point of positive charge will be in the distinctive side. The whole atom will be a polar particle.
Non-Polar Molecules: A particle which doesn't have the charges present toward the end because of the explanation that electrons are finely distributed and those which evenly counteract each other are the non-polar atoms. In an answer, a polar particle can't be blended in with the non-polar atom.
The electronegativity difference between $H$ and $O$ is $3.5-2.1=1.4.$ Hence, the type of bond formed is Polar covalent. In ${{H}_{2}}O~$ a hydrogen $\left( H \right)~$ atom is bound to a highly electronegative atom oxygen $\left( O \right)~$ such $H$ atom experiences electrostatic force of attraction to some other nearby highly electronegative atom (such as $O$ atom of second water molecule) to form a bond called hydrogen bond. Thus, water molecules have both polar covalent and hydrogen bonds.
Therefore, the correct answer is option D.

Note:
Remember that the bond or the sub-atomic polarities rely on the electronegativities of the particles or the atoms. An atom is essentially supposed to be a polar particle, non-polar particle or ionic atom. The two connections among oxygen and hydrogen are polar while that between two iotas are non-polar.
