Answer
See explanation below.
Work Step by Step
a.) SO2 would have the greater dipole moment because this is a polar molecule with a net dipole while SO3 is nonpolar due to all of its dipoles canceling out.
b.) IF would have a greater dipole moment because IF's electronegativity difference is (1.3) is larger than that of ICl (0.3)
c.) SF4 wold have the greater dipole moment because SF4 is a polar molecule with a net dipole while SiF4 is nonpolar due to its dipoles all canceling out.
d.) H2O would have a greater dipole moment because the electronegativity difference of O-H bonds (1.4) is greater than that of S-H bonds (0.4)
