Mechanism for the given transformation need to be drawn and if sodium hydroxide is present in large amount for transesterification. Concept introduction: Transesterification is a process in which the alcohol group present in the carboxylate of triglyceride is exchanged by another organic alcohol group. This can occur in presence of either acid or base as catalyst. The general scheme can be shown as, Please remember that transesterification using basic condition is done in few steps rather than acidic conditions. In presence of excess base the transesterification does not happen instead hydrolysis occurs. To draw : the mechanism for the given transformation.

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.

Concept Introduction:

Hydrolysis is a process in which the ester is converted to its respective carboxylic acid and alcohol in presence of aqueous acid or base. In case of triglyceride the hydrolysis results in formation of glycerol and three fatty acid units. In presence of other organic alcohol unit this hydrolysis occurs if the base is present in large amount rather than transesterification.

at 32.0 °C? What is the osmotic pressure (in atm) of a 1.46 M aqueous solution of urea [(NH2), CO] at 3 Round your answer to 3 significant digits.

Reagan is doing an atomic absorption experiment that requires a set of zinc standards in the 0.4-1.6 ppm range. A 1000 ppm Zn solution was prepared by dissolving the necessary amount of solid Zn(NO3)2 in water. The standards can be prepared by diluting the 1000 ppm Zn solution. Table 1 shows one possible set of serial dilutions (stepwise dilution of a solution) that Reagan could perform to make the necessary standards. Solution A was prepared by diluting 5.00 ml of the 1000 ppm Zn standard to 50.00 ml. Solutions C-E are called "calibration standards" because they will be used to calibrate the atomic absorption spectrometer. a. Compare the solution concentrations expressed as ppm Zn and ppm Zn(NO3)2. Compare the concentrations expressed as M Zn and M Zn(NO3)2 - Which units allow easy conversion between chemical species (e.g. Zn and Zn(NO3)2)? - Which units express concentrations in numbers with easily expressed magnitudes? - Suppose you have an analyte for which you don't know the molar…
