If the lone pair on this molecular model was removed, the molecule would most likely:
decrease the angle between the two bonded atoms (bonded atoms would be closer together)
increase the angle between the two bonded atoms (bonded atoms would be further apart)
there isn't enough information to be able to answer this question
keep the shape that it currently has
Which of the following statements is true about the molecule shown below?
The bonds are nonpolar and the molecule is polar.
The bonds are polar and the molecule is polar
The bonds are nonpolar and the molecule is nonpolar.
The bonds are polar and the molecule is nonpolar.
When lone pairs of electrons are present in a polar molecule, how are they arranged around the center atom—on the same side of the molecule or on opposite sides of the molecule?
same side of the molecule
opposite sides of the molecule
