A protic solvent consists of molecules that can act as hydrogen … WebbGeneral properties: Alkyl halides have higher boiling and melting points than corresponding alkanes. Alkyl halides are soluble in organic solvents but insoluble in water. The bond strength of C–X decreases as the size of X increases ⇒ iodine is a better leaving group than fluorine. Halogens are more electronegative than carbon atoms. lifeline rigid hospitals chennai
