Why is fluoromethane insoluble in water? © 2008-2010 http://www.science-mathematics.com . lower alkanes are slightly soluble in water but as carbon number increase solubility decrease coz non polar property increases.the are more soluble in non polar solvents like ether carbon tetrachloride and Naphtaline.water is polar solvent and dissolves polar solutes. Haloalkanes are alkanes that have a halogen (flourine, chlorine, bromine, iodine or astatine) in it in place of a hydrogen atom. Ask your question. Ask your question. For instance, methane has a solubility of 0.025 grams per Kg of water at 20 C.That is not very much.-No.Alkanes are generally non-polar....... lower alkanes are slightly soluble in water but as carbon number increase solubility decrease coz non polar property increases.the are more soluble in non polar solvents like ether carbon tetrachloride and Naphtaline.water is polar solvent and dissolves polar solutes. If a circle has area 32pi ft squared, then a 135 d.. Find a unit vector perpendicular to a = (-3, 6, 2).. More math help guys?? keywords: soluble,not,or,water,Why,in,alkanes,Are,why,Are alkanes soluble in water? Non-polar substances dissolve best in non-polar solvents, while polar solutes dissolve best in polar solvents. Expert from NTU answered your questions - watch here! In the case of alkanes the strength of the hydrogen bonds is too high so they will not dissolve. The Student Room, Get Revising and Marked by Teachers are trading names of The Student Room Group Ltd. Register Number: 04666380 (England and Wales), VAT No. In order to form hydrogen bonds a molecule should have a hydrogen tht is DIRECTLY attched to an elctronegative element such as oxygen,fluorine or nitrogen.In haloalkanes we dont have a hydrogen attched to an elctronegatve element , even if u consider some haloalkane with flurorne in it u would say it should form h- bonds but no it doest as F is not atthched to hydrogen rather a Carbon which in turn is attched to hydrogen but as i told in order for h-bonds to form Flourine should be DIRECTLY bonded to a hydrogen.
