Question

which of the following compound is expected to be the most ionic

Answer 1

the answer may be (b) pbCl4

Answer 2

Answer is (a) PbCl 2

   Option c and d are eliminated at first because the electronegativity difference between the atoms is much small making them covalent compounds.

   Among PbCl2 and PbCl4, PbCl4 has high charge and it attracts the electrons towards itself from high electronegative chlorine atom and will be covalent ...

  PbCl 2 will have electron pair attracted towards chlorine thus covalent character is reduced as electrons are not shared equally thus it reaches ionic character...

  Ask me if still any queries ....
