Text Solution

Verified by Experts
The correct answer is:
C

The elements of group 14 show an oxidation state of +4 and +2. The compounds showing an oxidation state of +4 forms covalent compound and have tetrahedral structures. e.g. SnCl 4 , PbCl 4 , SiCl 4 , etc. whereas those which show +2 oxidation state are ionic in nature and behave as reducing agent. e.g. SnCI 2 , PbCI 2 etc. Further as we move down the group the tendency of the element to form covalent compound decreases but the tendency to form ionic compound increases.
