Question

Arrange the following in the increasing order of covalent character. SiCl4 , CCl4 , SnCl4 , GeCl4

Answer 1

Answer:

Ccl4≤sicl4≤GeCl4≤Sncl4

Explanation:

Answer 2

Increasing order of covalent character is as follows.

     $SnCl_{4}$ < $GeCl_{4}$ < $SiCl_{4}$ < $CCl_{4}$

Explanation:

Covalent character is defined as the ability of an atom to share electrons with another atom. According to Fajan's rule, smaller is the size of cation and larger is the size of anion more will be covalent character.

This means that on moving down a group covalent character decreases. Also, effective overlap will decrease with increase in size of the non-metal so, sharing of electrons will not take place effectively.

Therefore, for the given compounds increasing order of covalent character is as follows.

     $SnCl_{4}$ < $GeCl_{4}$ < $SiCl_{4}$ < $CCl_{4}$
