An element 'X' belongs to fourth period and fifteenth group of the Periodic Table. Which one of the following is true ?
Updated On: Jun 7, 2024
- Partially filled 'd' orbitals and completely filled 's' orbitals.
- Completely filled 's' orbitals and completely filled 'p' orbitals
- Completely filled 's' orbitals and half-filled 'p' orbitals
- Half-filled 'd' orbitals and dompletely filled 's' orbitals

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Since the element 'X' belongs to fourth period and fifteenth group of Periodic Table, its outer electronic configuration is $ 4s^2 \, 4p^3$
Its complete electronic configuration is $ 1s^2, \, 2s^2, \, 2p^6, \, 3s^2 \, 3p^6, \, 4s^2, \, 2d^{ 10}, \, 4p^3 $Hence, its s. orbital is completely filled while p-orbital is half-filled.
Its complete electronic configuration is $ 1s^2, \, 2s^2, \, 2p^6, \, 3s^2 \, 3p^6, \, 4s^2, \, 2d^{ 10}, \, 4p^3 $Hence, its s. orbital is completely filled while p-orbital is half-filled.

Haloalkanes and Haloarenes - Classification
Classification of Haloalkanes and Haloarenes are as follows:
Haloalkanes and Haloarenes are Classified on the Basis of the Number of Halogen Atoms:
These are further classified as mono, di, or polyhalogen (tri-,tetra-, etc.) compounds depending on whether they contain one, two or more halogen atoms in their structures. For example;
- Monohaloalkane
- Dihaloalkane
- Trihaloalkane
Haloalkanes and Haloarenes are Classified on Compounds Containing sp3 C—X Bond (X= F, Cl, Br, I)
This class includes:
- Alkyl halides or haloalkanes (R—X)
- Allylic halides
- Benzylic halides
Haloalkanes and Haloarenes are Classified on Compounds Containing sp2 C—X Bond
This class includes:
- Vinylic halides
- Aryl halides
