MgCl_(2) is linear but SnCl_(2) is angular-explain.

1.	MgCl_(2) is linear but SnCl_(2) is angular-explain.
Answer» Solution :For `MgCl_(2),H=(1)/(2)[2+2-0+0]=(4)/(2)=2`, i.e., the central Mg-atom is sp-hybridised. Therefore, the molecule is linear. On the other hand, for `SnCl_(2),H=(1)/(2)[4+2-0+0]=(6)/(2)=3`, i.e., the cental Sn-atom is `sp^(2)`-hybridised. Therefore, the two bond pairs and one lone PAIR present in the molecule are directed TOWARDS the corners of an equilateral triangle. HENCE, `SnCl_(2)` molecule is angular.
