The O¬H bond lengths in the water molecule 1H2O2 are0.96 Å, and the H¬O¬H angle is 104.5°. The dipole momentof the water molecule is 1.85 D. (a) In what directionsdo the bond dipoles of the O¬H bonds point? In what directiondoes the dipole moment vector of the water moleculepoint? (b) Calculate the magnitude of the bond dipoleof the O¬H bonds. (Note: You will need to use vector addition to do this.) (c) Compare your answer from part (b)to the dipole moments of the hydrogen halides (Table 8.3).Is your answer in accord with the relative electronegativityof oxygen?

Question
The O¬H bond lengths in the water molecule 1H2O2 are
0.96 Å, and the H¬O¬H angle is 104.5°. The dipole moment
of the water molecule is 1.85 D. (a) In what directions
do the bond dipoles of the O¬H bonds point? In what direction
does the dipole moment vector of the water molecule
point? (b) Calculate the magnitude of the bond dipole
of the O¬H bonds. (Note: You will need to use vector addition to do this.) (c) Compare your answer from part (b)
to the dipole moments of the hydrogen halides (Table 8.3).
Is your answer in accord with the relative electronegativity
of oxygen?
