!. Which of the following structures would you expect to have a net dipole moment?
2. Rank the sp, sp2, and sp3 orbitals in order of decreasing (highest to lowest) energy.
d)they are all the same

i believe H2C O with the double bond is the only one with a dipole moment

HCtriplebondCH is linear and no dipole moment.
NH4^+ is tetrahedral and symetrical; therefore, no dipole moment.
H2C=O is not symmetrical in three dimensions; it has as dipole moment.
Same for BCl3.
For #2. here is come good reading.

i got the first one easy enough. the reading was interesting. so that leads me to believe b is the correct answer. thank you dr. bob
