Answer to Question #161623 in General Chemistry for Lyndale

Question

When trying to decide on the net polarity of a molecule (molecular dipole), you should consider:

the difference(s) in the electronegativities of bound atoms.

the symmetry or asymmetry of the shape of the molecule/bonds.

the symmetry or asymmetry of electrons around the molecule.

all of these.

none of these.

Answer 1

If a molecule is arranged asymmetrically and there is a significant difference in the electronegativities of bound atoms, the molecule can be considered as a dipole. Thus, we should the difference(s) in the consider electronegativities of bound atoms and the symmetry or asymmetry of the shape of the molecule/bonds.
