Question

Which one is most ionic?
a) P2O5
b) CrO3
c) MnO
d) Mn​2O7

Answer 1

Magnitude of positive charge is directly proportional to polarization power, is directly proportional to covalent character, is indirectly proportional to ionic character. as a MnO has lowest magnitude of positive charge so MnO is most ionic compound

Answer 2

Ans (c) Mno

Mno is the most ionic compound.

• Mno has the lowest magnitude positive charge hence Mno is the most ionic compound.

• Magnitude of the positive charge is directly proportional to Polarization power , directly proportional to Covalent character and indirectly proportional to ionic character.

• In determination of ionic character , electronegativity of the two atoms is involved. The greater the difference, more the ionic character in the bond.

•HF has highest percentage of the ionic character because of electrongativity of F.

• Ionic character increases down the group.

• Ionic character decreases across the row.
