The most common alcohol known as ethanol is used in alcoholic drinks fuel gasoline a preservative for biological specimens and a solvent for paints and drugs.
Organic compounds are represented shortly by the molecular formula and structural formula. This is due to stronger London forces because the ring shape allows for a larger area of contact. Solubility Alkenes are insoluble in water and soluble in organic solvents such as benzene etc.
Cycloalkanes are similar to alkanes in their general physical properties but they have higher boiling points melting points and densities than alkanes. They serve as fuels. Containing only CC and CH bonds unreactivity of cycloalkanes with little or no ring strain see below are comparable to non.
Hence the general formula for a. The compounds in which hydrogen atoms of an alkane is replaced by halogen is known as. Any of the saturated hydrocarbons with the general formula C n H 2n2 where C is a carbon atom H is a hydrogen atom and n is an integer is referred to as a paraffin hydrocarbon.
The general formula for the alkanes is C n H 2n 2 where n is the number of carbon atoms in the molecule. You can also read. Natural gas and petroleum contain a large amount of paraffin.
