Question

THE PRESENCE OF MOLECULAR DIPOLE MOMENTS Identify whether each of the following compounds exhibits mol lecula- dipole moment: so, indicate the direction of the net molecular dipole moment: (A) CH;CH-OCH CHz (B) COz

Answer 1

A. CH2=CH-OCH2CH3 is a polar molecule due to the presence of the C=O and C-O bonds, which are polar. The net molecular dipole moment would point from the oxygen atom to the hydrogen atoms.

B. CO2 is a non-polar molecule because the two oxygen atoms are symmetrically placed around the carbon atom, which creates a cancellation of the individual bond dipoles. So, CO2 doesn't have any molecular dipole moment.
