Solution: Which of the following molecules does not have a permanent dipole moment?a. water, H2Ob. acetone, CH3COCH3c. carbon dioxide, CO2d. sulfur dioxide, SO2e. chloromethane, CH3CI


Which of the following molecules does not have a permanent dipole moment?

a. water, H2O

b. acetone, CH3COCH3

c. carbon dioxide, CO2

d. sulfur dioxide, SO2

e. chloromethane, CH3CI


For a molecule to have a permanent dipole moment, the individual dipole moments of its bonds must not cancel out.

(a) H2O : Oxygen goes in the center since hydrogen can only form one bond. The Lewis structure for H2O is:
