Baeyer's Test for Alkanes

A Why are alkenes called unsaturated hydrocarbons. Alkanes are very feebly soluble in water but they are soluble in non-polar solvents such as Benzene CCl 4 etc.

Preparation of Hydrocarbons Alkanes From alkenes and alkynes.

. Add 1 alkaline potassium permanganate. B Alkaline potassium permanganate test Baeyers test. Cyclo alkanes Stabilities Baeyers strain theory limitation of Baeyers strain theory Coulson and Moffitts modification Sachse Mohrs theory Theory of strainless rings reactions of cyclopropane and cyclobutane only.

Take a little of the given organic compound to be tested in a test tube. 2 a The drying agent used in the laboratory preparation of HCl gas. Used in radical substitution and electrophilic addition reactions in organic chemistry.

H 2 gas is passed over a metal surface such as Ni Pt along with the alkenes to produce alkane. Used in organic chemistry as a qualitative test for the presence of unsaturation such as double bonds. Experiments involving laboratory techniques Recrystallization Steam distillation.

Reactants along the sides of a test tube forms a brown ring at the junction of the two liquids. Use of two different alkyl halides in Wurtz reaction always leads to a mixture of alkanes. Also acts as a mild oxidizer to oxidize benzylic or allylic alcohols.

The alkanes can be produced from alkenes or alkynes through hydrogenation. Dissolve the organic compound in 2ml of water or acetone in the test tube. Ii State the following.

Is an alkaline solution of potassium permanganate. Thus only symmetrical alkanes can be prepared by this method. B Products formed when ammonia is burnt in excess of oxygen.

The separation of these alkanes is difficult because there is only a little difference in their boiling points.
