Answer:
Predicting the polarity of a bond is the correct answer to this question.
Explanation:
Polar-covalent bonded substances have atoms that are distributed unequally among the central atom. The polarity of this bond is essentially determined by the bound atoms uniformly electronegativities.
To evaluate the polarity using numerical means of a covalent bond, if the result is between 0.4 and 1.7, then the bond is usually polar covalent.
