    Chemical bond From Wikipedia‚ the free encyclopedia A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electrostatic force of attraction between opposite charges‚ either between electrons and nuclei‚ or as the result of a dipole attraction. The strength of chemical bonds varies considerably; there are "strong bonds" such ascovalent or ionic bonds and "weak bonds" such as dipole–dipole interactions

So in this experiment‚ the Knoevenagel Condensation of diethyl malonate with aromatic aldehyde salicylaldehyde involves an initial aldol-type addition followed by a spontaneous dehydration. The final step forms a lactone ring‚ generating the heterocyclic ring system known as Coumarin. One of the best known synthetic coumarins is

The phenacyl effect applies to halides that are adjacent to a _-bond‚ such as a simple double bond‚ an aromatic ring‚ or a carbonyl. The neighboring _-bond stabilizes both SN2 substition and SN1 ionization (Figure

    Discussion The reaction through which 4-mrthaoxyacetophenone is converted to 4-methoxybenzoic acid is a haloform reaction. This reaction involves two distinct stages that occur in the same environment. The first stage occurs through the based-catalyzed halogenation of the ketone that forms a trihalo ketone. First‚ the bleach is transformed into chlorine and hydroxide ions through the following reaction: Then‚ the hydroxyl is able to attack the rather acidic (pKa ~ 20) α-hydrogen of the ketone

(1838). the problem was that salicylic acid was tough on stomachs and a means of ‘buffering’
