Ionic radii of
Ionic radii of
Updated On: Jun 14, 2022
- $Ti^{4+}$
- $^{35}_{}CI^- < \, ^{37}_{}CI^-$
- $ K^+ > CI^-$
- $P^{3+} > P^{5+}$
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
(a) $Ti^{4+} > Mn^{7+}$ is the correct order of size due to lower positive charge on $Ti^{4+}$.
(b) $^{35}_{}CI^- < \, ^{37}_{}CI^-$ : Isotopes with same charge have same size because isotopes differ in compositions of nuclei which
do not affect the atomic/ionic radius.
(c) $K^+ < Cl^-$ is the correct order. Among isoelectronic species, anion has greater size than cation.
(d) $P^{3+} > P^{5+}$ is the correct order. For the same elements, lower the positive charge, larger the ions
(b) $^{35}_{}CI^- < \, ^{37}_{}CI^-$ : Isotopes with same charge have same size because isotopes differ in compositions of nuclei which
do not affect the atomic/ionic radius.
(c) $K^+ < Cl^-$ is the correct order. Among isoelectronic species, anion has greater size than cation.
(d) $P^{3+} > P^{5+}$ is the correct order. For the same elements, lower the positive charge, larger the ions

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
