The synthesis that’s important to us is the knovenagel condensation (Figure 1) and the perkin reaction (Figure 2). The knovenagel condensation is named after Emil Knovenagel. The Knovenagel condensation is a key to the commercial production of the antimalarial drug lumafrantrine. The perkin reaction was develop by William

Units) Assume that a parcel of air is forced to rise up and over a 4000-meter-high mountain (shown below). The initial temperature of the parcel at sea level is 30°C‚ and the lifting condensation level (LCL) of the parcel is 2000 meters. The DAR is 10°C/1000 m and the SAR is 6°C/1000 m. Assume that condensation begins at 100% relative humidity and that no evaporation takes place as the parcel descends. 1. Calculate the temperature of the parcel at the following elevations as it rises up the

mountain‚ should the relative humidity of the parcel change as it rises from 2000m to 4000m? (a) No‚ the relative humidity should not change. (b) The elevation at which the parcel of air reaches its dep point temperature is called the lifting condensation level. The LCL in this example was 2000m‚ so the relative humidity is at 100% already. 6. As the air rises up the windward side of the mountain: (a) What is the capacity (saturation mixing ratio) of the air at 2000 meters? 7.6 g/kg (b) What

Purpose- This experiment illustrates the use of adol condensation for the synthesis of a five-membered carbocylic ring. It is also a good demonstration of the impact extended conjugation has on the absorption of visible light. The reactants are bright yellow in color while the products are a very deep purple color appearing almost black. Introduction- The synthesis of Tetraphanylcyclopentadienone was a further example of the adol condensation reaction. Tetraphenylcyclopentadienone was the final
