Mechanism for the tautomerization process that occurs under acidic conditions has to be drawn. Concept Introduction: Keto-enol tautomerization occurs when a hydroxyl group is present next to a double bond in presence of acid or base. Due to this the ketone will have few amount of enol also. The quantity of ketone and enol is determined only by equilibrium. Acid catalyzed tautomerization: Compounds that are ketone can undergo keto-enol tautomerization in presence of acid. Tautomers are not same as resonance structures. The chemical properties of tautomers will be different. A general mechanism of keto-enol tautomerization that occur in acidic condition can be given as, First step is the formation of carbocation. Second step is the formation of double bond between oxygen and carbon atom. The water acts as a base and abstracts a proton to form the final keto compound.

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone

C This question shows how molecular orbital (MO) theory can be used to understand the chemical properties of elemental oxygen O₂ and its anionic derivative superoxide Oz. a) Draw the MO energy diagram for both O2 and O2. Clearly label your diagram with atomic orbital names and molecular orbital symmetry labels and include electrons. Draw the Lewis structure of O2. How does the MO description of O2 differ from the Lewis structure, and how does this difference relate to the high reactivity and magnetic properties of oxygen? ) Use the MO diagram in (a) to explain the difference in bond length and bond energy between superoxide ion (Oz, 135 pm, 360 kJ/mol) and oxygen (O2, 120.8 pm, 494 kJ/mol).

Which configuration seems more stable at this point of the analysis? (Note that 349.76 cm = 1 kJ/mol) Exchange energy (IT) was not taken into account in part (d), but it plays a role. Assuming exchange an occur within t29 and within eg (but not between tz, and ea), how many exchanges are possible in the low in configuration vs in the high spin configuration?
