C8H18(octane) is non-polar with intermolecular van der Waals bonding. C2H5Cl (chloroethane) is polar with intermolecular dipole-dipole and van der Waals bonding. H2O (water) is polar with intermolecular dipole-dipole, van der Waals and hydrogen bonding. C2H5F (fluoroethane) is polar with intermolecular dipole-dipole and van der Waals bonding. C9H20 (nonane) is non-polar with intermolecular van der Waals bonding. The misibility with C8H18 (octane) decreases with polarity of the molecule: C9H20 (nonane) > C2H5Cl (chloroethane) > C2H5F (fluoroethane) > H2O (water) Solution C8H18(octane) is non-polar with intermolecular van der Waals bonding.
