Answer to Question #335979 in General Chemistry for ngoma

Question

4. Give one example of a compound having a linear molecular structure that has an overall dipole moment (is polar) and another example of a linear molecule that does not have an overall dipole moment (is non-polar). Do the same for molecules that have trigonal planar and tetrahedral molecular structures.

Answer 1

The linear molecular structure that has an overall dipole moment  is HCl, example of a linear molecule that does not have an overall dipole moment is CO2, BF3 is trigonal planar, polar molecule and O3 is nonpolar, trigonal planar. CH4 is nonpolar tetrahedral molecule and NH3 is polar tetrahedral molecule.
