Problem 10.57

Which molecule in each pair has the greater dipole moment? Give the reason for your choice. (a) SO2 or SO3 (b) ICl or IF (c) SiF4 or SF4 (d) H2O or H2S

                                                                Step by Step Solution

Step 1 of 4

a)

The structure of  and   are as follows.

The shape of  is bent and  is trigonal planar.

The electronegativity  of  sulfur = 2.5

The electronegativity of oxygen = 3.5.

Hence there is electronegativity difference for  bond.

But bond dipole of cancelled together in  due to its planar structure.

Therefore,   is polar then .
