(a)
Interpretation:
The substance with larger dispersion forces needs to be determined.
C8H18, Octane, C2H6 and Ethane
Concept introduction:
Dispersion forces sometimes are known as London Forces, induced-dipole forces, van der Waals forces or London Dispersion forces. They are induced-dipole forces which develop from variations within the electron’s arrangement around the molecule. Even molecule which is non-polar will not contain the perfect dispersal of charge for every moment of time.
(b)
Interpretation:
The substance with larger dispersion forces needs to be determined.
HCl or HI

Even molecule which is non-polar will not contain the perfect dispersal of charge for every moment of time.
(c)
Interpretation:
The substance with larger dispersion forces needs to be determined.
H2O or H2Se
