Similarity in chemical properties of the atoms of elements in a group of the Periodic table is most closely related to :
Updated On: Jul 29, 2024
- atomic numbers
- atomic masses
- number of principal energy levels
- number of valence electrons
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
If elements are arranged in order of their increasing atomic numbers, element coming at intervals of $2,8,8,18,18,32$ and $32$ will have similar physical and chemical properties and thus grouped in one particular group.

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
