Question

Which of the following are applications of electronegativity?

• A. Prediction of polarity in a molecule
• B. Predicting basic nature or acidic nature of oxides
• C. Strength of the bond
• D. all of the above

Answer 1

The correct option is D all of the above

A) Greater the electronegativity difference, greater the polarity.
B) In $M-O-H$, if the electronegativity difference is greater in M-O than O-H , then the hydroxide will act as a base. if the electronegativity difference is lesser in M-O than O-H , then the hydroxide will act as an acid.
C) Greater the electronegativity difference, greater the bond strength. For example HF has higher bond strenght than HI.
