1.	Arrange n-pentane, isopentane and neopentane in the descending order of dispersion forces.
Answer» Solution :London forces of ATTRACTION is proportional to the surface area of molecules. With INCREASING branching MOLECULE gets spherical shape which has minimum surface area and as a RESULT London forces decreases. Order of London forces is : n-pentane `gt` isopentane `gt` neopentane.
