Which of the following statements is NOT true in regards to water, ethanol, and isopropanol?
A. Two lone pairs of electrons are assigned to the oxygen in each Lewis structure of all three molecules.
B. H-O-H and C-O-H bond angles are all equal to 1095.
C. Dispersion forces affect all three molecules.
D. Water has the highest boiling point.
E. All of these are true.
I don't know the bond angles for COH in ethanol and isopropanol but I know the bond angle in water is 105 degrees so I would pick B. By the way, I'm sure you intended to write 109.5 and not 1095 and you omitted the units.
