- How many sites of diversity are there in this combinatorial library? NN NN HN `NH2 он `NH2 6 4 8 3What is the point group for molecule C? I already found the point group for molecule A (C2h) and B (C2v), but I'm not sure which one is CThe point group C2y has four operations: E, C2, 0v and oy. Taking water as an example for the point group with oy as the molecular plane, what operation is equivalent to oyand C2 performed consecutively ?
- Determine the major axis of symmetry for the following 2-dimensional shape: (А) С, (В) С, (С) С, (D) C6Identify the symmetry species of the Symmetry Adapted Linear Combination (SALC) ? = ?′ − ?′′ in the C2v molecule NO2, where ?′ is a 2px orbital on one O atom and ?′′ is a ???? 2px orbital on the other O atom.Inversion is not a symmetry operation of methane.Explain.
- Consider the character table given below for the point group D3h, which includes molecules like cyclopropane and BF3. Suppose has been already determined a reducible representation for the collective motions of one such molecule, Γ(3N). What combination of irreps should we remove from it to account for translations & rotations, thereby yielding the purely vibrational representation, Γvib?2. We can form a group of symmetry operations, with our operation being do one operation and do another. For a molecule with an isosceles triangle molecule like water, we talked about the 4 symmetry operations as E (do nothing), C2 (rotation by 180°), σv (the reflection of one hydrogen to the other), and σv’ (the reflection from front to back). By putting coordinates on each of the three atoms (z points along the C2 rotation axis, x points from one hydrogen to the other, and y points out of the plane of the molecule) find the “multiplication” table for this group.Which of the following 3 point molecules has the greatest hyperconjugation effect? C een A Br B Br Br Br
