Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The electronic configuration of the element with atomic number 117 is
= [ $ R_n ]_{ 86 } 5 \, f^{ 14 }, \, 6d^{ 10 }, \, 7s^2, \, 7p^5 $
This element contains 7 electrons in its outermost shell, so it belongs to VIIA (17) group of Periodic Table, i.e., it is a halogen. Its IUPAC symbol is Uus.

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
