- Sodium hydroxide was used to help separate benzoic acid and fluorenone because deprotonated benzoic acid (sodium benzoate) favorably partitions into the aqueous phase (and fluorenone does not). Would this procedure have worked without the sodium hydroxide (using simply neutral water)? Why or why not?TLC, a powerful analytical tool, can be used to monitor the progress of reactions. The synthesis of ethyl-3-coumarincarboxylate can be monitored by TLC by displaying the starting aldehyde 1, and coumarin product 2, which have very distinct Rf values (Hint: Think about the polarity of compounds 1 and 2 in terms of their abilities to H-bonds to silica gel). What can be determine about the progress of the reaction from analysis of the TLC shown below?What is the major difference between catalytic reduction and non-catalylic reduction techniques?
- Friedel-Crafts Alkylation, based on substituted benzene reaction, including reactivity based on electron donating and withdrawing group and also discuss the possible positions (Ortho, Meta and Para) for the new group. Explain if there is polysubstitution occurs. Keeping the reaction mixture in the ice bath and adding the reagent slowly by continuously stirring is the key point of success.Draw and label the full catalytic cycle for the Suzuki Cross-Coupling of 4-bromobenzyl alcoholwith phenylboronic acid. Please include the oxidation state of the Pd atom for each step.In UV spectroscopy we are taught the effects of polarity on liquid chemistries that may undergo bathochromic red shif, hypochromic blue shift , hypsochromic decrease in absorbance and aborptivity and hyperchromic effects a increase in absorbance or absorptivity. The cause for hyperchromic shifts has one explanation that appears to make sence and that is related to Auxochromic groups or the effect on the chromophore for for a new chromophore with the auxo group that causes both a hyperchromic and bathochromic red shift. Question 1: Does this dual shift in absorbance and wavelength occur in non-liquid sustances like plastics e.g. polypropylene, polyethylene, condensation polymers like PET and Polycarbonate? Question 2: Is there a way to predict level of hyperchromic shift based on the auxochromic group or do we need to know the chromophore? Question 3: Are there known examples of chromophore and Auxochromic groups that provide various molar extinction or absorptivity or absorbance…
- Describe how the product is purified. 4,4'-DIBROMOBIPHENYL [Biphenyl, 4,4'-dibromo-] Submitted by Robert E. Buckles and Norris G. Wheeler1. Checked by R. S. Schreiber, Wm. Bradley Reid, Jr., and Robert W. Jackson. 1. Procedure In a 15-cm. evaporating dish is placed 15.4 g. (0.10 mole) of finely powdered biphenyl (Note 1). The dish is set on a porcelain rack in a 30-cm. desiccator with a 10-cm. evaporating dish under the rack containing 39 g. (12 ml., 0.24 mole) of bromine. The desiccator is closed, but a very small opening is provided for the escape of hydrogen bromide (Note 2). The biphenyl is left in contact with the bromine vapor for 8 hours (or overnight). The orange solid is then removed from the desiccator and allowed to stand in the air under a hood for at least 4 hours (Note 3). At this point, the product weighs about 30 g. and has a melting point in the neighborhood of 152°. The crude 4,4'-dibromobiphenyl is dissolved in 75 ml. of benzene, filtered, and cooled to 15°. The…What are regioselectivity and stereospecificity of E2 reactions? Can somebody please explain them to be with examples?The mass of nitration product is 0.50 grams, and melting range of the nitration product is 99 -101 degrees C.
