Organic Chemistry Virtual text....

[java]

A  very good source of organic chemistry terms , reactions and mechanics of different functional groups,

Example

acetals
acetoacetic ester alkylation
acceptor reactant in the aldol reaction
achirality
achiral diastereomer
aci-anions   from nitroalkanes
acid-base catalysis
acid-base equilibria
acidity constant Ka
acidity
       equilibrium acidity
       solvent effects   DMSO pKa'a
       carbon acids
       hydrogens
       stereoelectronic factors in enolization
       kinetic acidity
       base catalyzed isotope exchange
       of nitroalkanes
       structural reorganization factor
       hybridization
       inductive effects
       resonance stabilization of carboxylate anion
       super acid
activating substituents
activation energy

...............and so on, good learning stuff...java
