Updated On: Aug 1, 2024
- CsF
- LiF
- NaF
- CsI

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The order of size of given cations is ${Li^{+} < Na^{+} < Cs^{+}}$ and the order of size of given anions is ${I^{-} > F^{-}}$ .
Thus, when the cation is largest and anion is smallest, the cation to anion size ratio is maximum. Hence, cation to anion size ratio is maximum for $CsF$.
Thus, when the cation is largest and anion is smallest, the cation to anion size ratio is maximum. Hence, cation to anion size ratio is maximum for $CsF$.

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:
