2. what's the relationship between a molecule's bond dipole and the electrostatic potential ?

three atom module

select: bond dipole, molecular dipole, & partial charge.

3. what is the effect of changing the relative electronegativity of an atom and the molecule's bond dipole ? molecular dipole ?

4. relate the molecule's bond dipole and its molecular dipole. hint: vector addition

real molecules module

select: bond dipoles, molecular dipole, & electrostatic potential

5. toggle between 'electrostatic potential' and 'electron density' for a variety of molecules. what is the relationship between electrostatic potential and electron density ?

6. relate the molecule's bond dipole and its molecular dipole. what is the prerequisite to relating a molecule's bond dipoles and its molecular dipole ? hint: vector addition

7. relate a molecule's dipole and the electrostatic potential.

8. there are nine nonpolar molecules. identify the polar versus nonpolar molecules. how to differentiate between a polar versus nonpolar molecule based on its molecular dipole ?
