The concept of polarity” is due to?

The concept of polarity” is due to

1. one atom of a bonded pair of atoms ex-

erting a greater attractive force on the shared

electrons.

2. the number of electrons shared by any

pair of atoms.

3. similarities in attractions for shared elec-

trons when the electronic and molecular ge-

ometries are the same.

4. the optimal Lewis dot structure for any

pair of atoms.

5. atoms that are bonded together but have

unequal numbers of lone pair electrons.
