Is heptane soluble in water and why?

Answer 1

No hexane is insoluble in water. "Like dissolves like" meaning the more alike (chemically) two things are the more likely they will be soluble in each other. Hexane and water are just chemically too different.

Hexane has a very low solubility in water, just a few mg/l. For most purposes it can be considered insoluble. However in one very important aspect it must not be considered insoluble. The vapour pressure of hexane above water containing just a few mg/l is as great as above pure hexane and can lead to explosive atmospheres.

Answer 2

No, heptane, like other hydrocarbons is insoluble in water.

Answer 3

It is not soluble because there are 7 Carbon's. Under 6 C's is soluble.
No. C5H11-CH(=O) (Chloroform) is insoluble in water

Answer 4

As the hydrocarbon part increases in organic compound its polarity becomes decreased so solubility in water also becomes decreased so heptanal is less soluble.

Answer 5

Only very slightly. Wikipedia lists it as "immiscible."

Answer 6

Because heptane has a non-polar molecule it is not miscible with water.

Answer 7

Heptane is not soluble in water because it is nonpolar, while water is polar. The molecules of heptane are not attracted to the water molecules, making it insoluble in water.

Answer 8

Yes.
