Why do chlorophyll a and chlorophyll b have different Rf values? (Why is chlorophyll a slightly more soluble in solvent than chlorophyll b?)
Explain how enzymes are able to differentiate between two molecules that have similar shapes and chemical groups like valine and threonine.
(a) The two molecules below are structurally similar, however, one of these molecules is much more acidic than the other. Identify this molecule, draw the conjugate base and briefly explain the basis of its increased acidity 2.

Postlab Questions 1. How fumaric acid and maleic acid are structurally different compounds and how that affects their physical and chemical properties. 2. Include drawings of the structures of maleic and fumaric acid to illustrate your point, 3. Calcuate the reaction yield. Show all calculations. 4 Although maleic and fumaric acid are two different isomers, cis and trans isomers of succinic acid (HOOC-CH2-CH2-COOH) do not exist. Explain and use drawings of all molecules to illustrate your argument. 5 Which of...
3. How would you differentiate between the following pairs of molecules using 'H and C NMR? a) OI b) H3C CH3 он Vs CH3 CH3 VS Br Br
Is chlorophyll the only light-absorbing pigment in the chloroplast? How might this affect the observed absorption spectrum of chlorophyll versus the entire chloroplast? Is light absorbance the same thing as rate of photosynthesis? What is the difference between an Absorption Spectrum and an Action Spectrum?
1. Describe how the functional units for beta carotene, xanthophyll, chlorophyll A, and chlorophyll B are different. Be sure to identify the subunits that adhere to paper during chromatography, 2 Describe a technique for measuring photosynthetic rate. 3 Many deciduous trees have leaves that turn yellow in the fall. What do you suppose is happening in the leaves at the cellular and molecular level? 4. Chloroplasts and mitochondria are both unusual in that they have double membranes and contain their...
Differentiate between the LCAO approximation 1 and LCAO approximation 2. Illustrate how these 2 approximations pertain to the orbitals of the homonuclear molecules diborane(Br2) and difluorine(F2). Explain the origin of the different energy ordering of the molecular orbitals in these two molecules. Explain what is meant by the following two terms used in molecular orbital theory. In both cases use molecular hydrogen (H2) to illustrate your answer. (G) LCAO (ii) HOMO ii) Differentiate between the LCAO Approximation 1 and LCAO...
