Answer:
The electronegative differences between the two atoms that make up a bond determine the bond's polarity. The sharing of valence electrons between the atoms forms a covalent bond. Polar, non-polar, or ionic covalent bonds are all examples of covalent bonds.
Explanation:
The one in which the electronegativity difference is maximum will possess the maximum polarity.
- Cl is chlorine and it belongs to group 17.
- P is phosphorus and it belongs to group 15.
- D is deuterium and it is an isotope of hydrogen.
- O is oxygen and it belongs to group 16.
Deuterium belongs to the hydrogen family, so it is not electronegative as much as the elements of periods 2 and 3 i.e., oxygen, phosphorus, and chlorine.
In a periodic table down the group, the electronegativity of an element increases.
Thus, phosphorus and chlorine belong to period 3 so they are more electronegative than oxygen which belongs to period 2.
Along a period, the electronegativity of an element increases. Thus, chlorine is more electronegative than phosphorus.
Therefore, chlorine is the element that will form the H-X bond with maximum polarity as the electronegativity difference between hydrogen and chlorine is the most.
Hence, the correct option is (a) Cl.
