#Hattenthecurve #lattenyourmarks 4 1. Consider ethylene C,H, which has a Ded symmetry group. We now want to change the symmetry group by cutting it in half (through the double bond) and substituting one half by a molecular fragment. C2H, CH? Find a substituent molecular fragment with less or equal to 6 atoms such that the symmetry group of the new molecule has the following symmetry groups as denoted in (a), (b) and (c)! You can be...

Which of the following statements describes the theory of Conservation of Orbital Symmetry? Select one: A. The molecular orbital of the transition state must be similar to that of the product. B. A pericyclic reaction requires the overlap of in-phase orbitals. C. The molecular orbitals of reactant and product must have different symmetry. D. Only s orbitals from reactants and products are utilized. E. The molecular orbital of the transition state must be similar to that of the reactant.

I think I can pinpoint my confusion a bit better. Here comes my updated question (I'm not sure what the standard way of doing things is - please let me know if I should delete the old version). The major change is that I removed focus from the third question which probably is a purely mathematical question (in the notation below, it asks what properties of (M,T) together with (M,T) being consistent, forces (M,T) to be unique.). Say that a...

3.(adapted from Prob. 3, p. 103, Brown's Introductory Physics I) A baseball of mass m, is dropped at time t0 from rest (' 0) from the top of Alfred's Davis Memorial Carillon (which has height H) and falls freely under the influence of gravity. At the same instant (t 0), a second baseball of mass m, is thrown up from the ground directly below with speed vo2 (so if the second ball travels far enough, fast enough, they will collide)....

Group think is one of the dangerous missteps in the decision-making process. As a member of a long-standing policy committee at work, I would take the following steps to avoid any “groupthink” symptoms: Invite external perspectives- the decision-making step should protect the external perspectives which helps in incorporating the decisions in the group’s thinking. Anticipate – The important trait of a good manager is to possess anticipating skills. I would anticipate possible Groupthink so that I can develop strategies to...
