E-DRAW

How many different compounds can be produced when naphthalene, C 0Hjj (30), undergoes electrophilic aromatic substitution by a single electrophile (denoted E) Draw stick figures to represent them. 

Find the composition of the raffinate leaving the first stage, n by judging the position of the tie-line from e. Draw a line from the pole point, P, through r to cut the curve at e2, the extract leaving stage 2. 

In parts (c), (d), and (e) draw the F(t) curves predicted on the basis of the various models so that they may be compared with the experimental data. 

E—Drawing one or more Lewis structures may help you. Only C and E are polar. Only the ammonia has hydrogen bonding, which is very, very polar. 

Problem 7.20 Optically pure (S)-(-i-)-CH3CHBr-n-CjH,3 has [a] = -1-36.0°. A partially racemized sample having a specific rotation of -i-30° is reacted with dilute NaOH to form (R)-(-)-CH,CH(OH)-n-CsH,3 ([ ] =-5. 97°), whose specific rotation is -10.3° when optically pure, (a) Write an equation for the reaction using projection formulas, (b) Calculate the percent optical purity of reactant and product, (c) Calculate percentages of racemization and inversion, (d) Calculate percentages of frontside and backside attack, (e) Draw a conclusion concerning the reactions of 2° alkyl halides. (/) What change in conditions would increase inversion ... 

Problem 21.22 Peptides are polyamides, like the product in Problem 21.15(e), Draw the structural formula for (a) a dipeptide, (h) a polypeptide unit of alanine (indicate the mer). 

FIGURE 15-34 Flux control coefficient, C, in a branched metabolic pathway. In this simple pathway, the intermediate B has two alternative fates. To the extent that reaction B —> E draws B away from the pathway A —> D, it controls that pathway, which will result in a negative flux control coefficient for the enzyme that catalyzes step B —> E. Note that the sum of all four coefficients equals 1.0, as it must. 

Project I Write a MATLAB m file that draws the surface z = f Kc, y) with / defined in equation (3.17), i.e., draw the top surface of Figure 3.14 alone. Repeat for the top surface of Figure 3.17 as well. 

We have a strong base, so we know the reaction wall go through an E2 mechanism, rather than an El mechanism. Therefore, the reaction will be stereospecific. So w e draw the Newman projection ... 

If the earlier patent application was to the same inventive entity then 102(a) and 102(e) would not apply since those sections apply to the work of another. However, exclusions under 103(c)/102(e) draw their usefulness from the fact that very often in an organization or within a group working together under a research collaboration, different or at least overlapping groups of inventors may work on related aspects of a project such that multiple patent applications may be filed over a period of time where each patent application lists a different inventive entity. In addition, the publication date of the first application is also important since it cannot be antedated in the patent world outside the United States. 

Model uncertainty is principally based upon (1) modelling errors (i.e. non-consideration of parameters) and (2) relation (dependency) errors (i.e. drawing incorrect conclusions from correlations). For example, the mathematical formula of a model describing the concentration-time curve of a substance emitted from, for example, glue should consider an algorithm that describes the time-dependent increase of the substance in a room, its distribution and the decrease of the concentration. Body weight correlates non-linearly with...
