Expert Answer

Step 1

Out of the given molecules SF4, PF3 and SCl2 will have a resultant dipole moment due to their arrangement of atoms. In case of CF4 and SF6 the dipoles cancel each other and overall these structures do not possess any dipole moment.

Step 2

SF4 has a see-saw structure and hence the molecule is polar and has a dipole moment.

PF3 has a trigonal pyramidal structure with 1 lone pair and hence it makes the molecule polar and possess a dipole moment.

SF6 has an octahedral structure and hence the polarities of the bonds cancel each other.

CF4 has a symmetr...
