Compare ZnCl 2 and MgCl 2 and find which is more soluble in organic solvents? (atomic number of Zn = 30 and that of Mg = 12 )
Options
- AZnCl 2
- BMgCl 2
- CZnCl 2 and MgCl 2 have same solubility
- DZnCl 2 and MgCl 2 are insoluble in organic solvents.
Correct answer
A. ZnCl 2
Step-by-step solution
As we know that according to solubility rule : Like dissolves like means. Polar dissolves with polar and non-polar dissolves with non-polar. Ionic compounds are more polar as compared to covalent compound and water acts as best polar solvent in which ionic compound will be more soluble in water or in aqueous medium. According to like dissolve like concept, more covalent is more soluble in organic solvent. So, ZnCl 2 is more covalent as MgCl 2 . Size : r M g + 2 > r Z n + 2
