And as Cl gains an electron, the forces between the electrons increases, causing them to expand and making the ion bigger. • 2 comments ( 32 votes) Luke Bayler 11 years ago fishers optical north canton

"WitrynaHexane has stronger IMF's than cyclohexane since it has more hydrogen atoms to hydrogen bond with. Hexane has stronger IMF's than cyclohexane due to its higher molar mass. Cyclohexane has stronger IMF's than hexane due to its shape. The IMF's are the same strength since they both have weak dispersion forces. Question " - Imfs of hexane
