Chemical Bonding And Molecular Structure Question 472
Question: Which of the following has been arranged in order of increasing covalent character-
Options:
A) $ KCl<CaCl_2<AlCl_3<SnCl_4 $
B) $ SnCl_4<AlCl_3<CaCl_2<KCl $
C) $ AlCl_3<CaCl_2<KCl<SnCl_4 $
D) $ CaCl_2<SnCl_4<KCl<AlCl_3 $
Show Answer
Answer:
Correct Answer: A
Solution:
-
According to Fajan’s rule Covalent character $ \propto $ charge on cation or anion Thus, the correct order is
$ {K^{+}}<C{a^{2+}}<A{l^{3+}}<S{n^{4+}} $ $ KCl<CaCl_2<AlCl_3<SnCl_4 $
