Concept explainers
Interpretation:
The relative differences in electro-negativity should be used to show the polarity in the given molecules.
Concept introduction:
Polar molecules are those in which distribution of electrons is not even.
Answer to Problem 56A
Explanation of Solution
Polar molecules contain polar bonds because of difference in electro-negativity between bonded atoms.
In H-F bond, F is more electronegative, in H-Br, Br is more electronegative, in N-O, O is more electronegative and in C-O, O is more electronegative.
Thus, the positive and negative charges are represented as follows:
