Question

6. Which of the following molecules and ions contain polar bonds? Which of these molecules and ions have dipole moments? (14 pts) (a) CIF (b) (b)CIO, (c) (c)sia- (d) Pc (e) SeF (t) PH, (g) Xef 7. Draw the Lewis structures and predict the shape of each compound or ion (8 pts) (a) so, (b) No, (c) so, (d) so, 8. A molecule with the formula AB2, in which A and B represent different atoms, could have one of two different shapes. Sketch and name the two different shapes that this molecule might have. Give an example of a molecule or ion that has each shape. (4 pts)

Explanation / Answer

polar bonds --> unequal share of electrons

electronegativity differnece --> if more than 0.2-0.5 then this is polar

a)

ClF3 --> polar bond between Cl-F

b)

ClO2- = polar bonds between Cl-O

c)

polar bonds between Si-Cl

d)

pola bonds betwee P-Cl

e)

Se-F6 polar

f)

P-H = nonpolar

g)

XeF4 = N/A

now... dipoles: overall dipole msut be accounted

a)

ClF3 --> polar, due to lone pair presence of Cl

b)

ClO2- = polar bonds between Cl-O

Polar dipole

c)

polar bonds between Si-Cl

dipole due to lone pair

d)

pola bonds betwee P-Cl

this is nonpolar, since P-Cl cancel each other

e)

Se-F6 polar

nonpolar, there is no net dipole formation

f)

P-H = nonpolar

polar, due to lone pair presence

g)

XeF4 = N/A

this is nonpolar, the arrangement of electrons will not allow dipole formation
