The maximum covalency of a non-metallic group 15 element 'E' with the weakest E-E bond is:
Show Hint
- 6
- 5
- 3
- 4
The Correct Option is D
Solution and Explanation
Group 15 elements (such as nitrogen, phosphorus, arsenic, etc.) can form covalent bonds with other elements, and the maximum covalency typically corresponds to the number of bonds that can be formed.
For a non-metallic element in group 15, the maximum covalency is usually determined by the number of available orbitals for bonding.
- Nitrogen, the lightest element in Group 15, has the weakest E-E bond due to its small atomic size and high electronegativity, which limits the number of bonds it can form.
- Phosphorus, arsenic, and other heavier elements in the group can form a maximum of 4 bonds due to their larger atomic size and availability of d-orbitals for bonding.
Thus, the correct answer is that the maximum covalency for a non-metallic Group 15 element with the weakest E-E bond is 4.
