PPT-Nucleophilic Addition Reactions

Understand the reactions of carbonyl compounds with HCN in the presence of KCN as a nucleophilic addition reaction using curly arrows relevant lone pairs dipoles and evidence of optical activity to show mechanism. Felkin. , . Ahn. and Friends. “These observations are, to my knowledge, the first definitive experimental evidence that further synthesis with asymmetric systems proceeds in an asymmetric manner. Although this statement does not at all contradict theory, it by no means follows from it”. Dr. Talat R. Al-Ramadhany. Introduction . Aldehydes are compounds of the general formula . RCHO. ;. Ketones are compounds of the general formula . RR´CO. . The groups R and R´ may be aliphatic or aromatic. . Physical Properties of Alkanes. Non polar compounds. Insoluble in water. Less dense than water and so will float on top of the water. Dissolve in organic solvents . . (. eg. dry cleaning fluid) and in each other (. Free Radicals. Chain Free Radical Reactions. Nonchain. .
