Question:medium

Arrange the following in the increasing order of their covalent character.
\[ CaF_2;\; CaCl_2;\; CaBr_2;\; CaI_2 \]

Show Hint

Larger anions are more polarizable and increase covalent characterAlways apply Fajan's rule in such questions.

Updated On: May 6, 2026

\( CaF_2 < CaI_2 < CaBr_2 < CaCl_2 \)
\( CaF_2 < CaCl_2 < CaI_2 < CaBr_2 \)
\( CaCl_2 < CaF_2 < CaBr_2 < CaI_2 \)
\( CaF_2 < CaCl_2 < CaBr_2 < CaI_2 \)

Show Solution

The Correct Option is D
