What types of IMF would you expect to occur between molecules of Benzoic acid?
What types of IMF would you expect to occur between molecules of Benzoic acid?
What would be difference between the IRs of p-toluic acid (starting material) and 4- (bromomethyl)benzoic acid (product)? (You don’t need to look up the IR of p-toluic acid, just think about what is changing between the starting material and product). Why is IR not a good way to verify that you made product?
What types of outliers might you expect to occur in the following data sets: (a) Student grades. (b) Salary data.
Benzoic acid has anti-microbial activity but benzoate does not. Based on the pKa of benzoic acid (4.2) , what types of foods would be well preserved with benzoate?
Choose all types of IMF that would be exhibited by the substance shown. (More than one answer may apply!) FOR ALL THESE DOWN BELOW. Question 9 2 pts Choose all types of IMF that would be exhibited by the substance shown. (More than one answer may apply!) CCI2F2 Hydrogen Bond lon-Dipole London Dispersion Forces (LDF) Dipole-Dipole Question 10 2 pts Choose all types of IMF that would be exhibited by the substance shown. (More than one answer may apply!) C3H7OH...
ochem* proton NMR What would you look for in the NMR spectrum of benzoic acid that would confirm its presence?
At what pH would an aqueous solution of benzoic acid be present as 99% conjugate base (benzoate)? (Hint: you will need to know the pKa of benzoic acid)? At what pH would an aqueous solution of m-nitroaniline be present as 99% conjugate acid (m-nitroanilinium, the protonated form)?
5. At what position and on what ring would you expect bromination of benzanilide to occur? Explain by drawing resonance structures of the intermediates.
A. For the recrystallization lab, you had 1.0 grams of benzoic acid. What volume of water would it take to dissolve the sample at 100 °C given the solubility data below for benzoic aid in water? You cool the solution of the given volume of water from part a to 0 °C, what mass of benzoic acid remains dissolved in the solution and what mass precipitates out? b. If you then let the solution increase to 25 °C, what mass...
1) What types of amino acids would you expect to find in the membrane-spanning region(s) of a membrane protein? Why? 2) What is the connection between “surface area-to-volume ratio” and cell size? Why are unicellular organisms much more limited by this (in general terms, why do they have to be small?)? 3) What is the difference between general transcription factors and transcriptional regulators? If you compared one of each type, which would you expect to be more abundant in...
What types of signal sequence(s) would you expect to find on each of the following types of proteins: Na+/K+ Pump DNA Polymerase Mitochondrial chaperone protein Flippases A lysosome localized protease
