How polar is heptane
Nettet29. mar. 2009 · All alcohols are polar.Because of the strenght of the attraction of the OH group, first three alcohols (methanol, ethanol and propanol) are completely miscible. They dissolve in water in any ... NettetIt is structurally a hexane molecule with a methyl group attached to its second carbon atom. It exists in most commercially available heptane merchandises as an impurity but is usually not considered as impurity in terms of reactions since it has very similar physical and chemical properties when compared to n-heptane (straight-chained heptane).

NettetWhen it comes to organic solvents (i.e., solvents containing CH bonds), they're nearly all miscible with one another. One notable exception is methanol and heptane or hexane, which will separate at some point. This is just what I've observed, 2adn's explanation of polarity being a range is good. 2 [deleted] • 6 yr. ago Thank you!
