- In your own words, explain why an object that has more symmetry elements is said to have higher symmetry than an object with fewer symmetry elements.arrow_forwardDoes the following structure represent a meso compound? If so, indicate the symmetry plane.arrow_forwardQ.2Identify the symmetry elements belonging to the following molecules for the appropriate operation; and write it above the arrow (one step). B₁ B₂ B3 B3- B₂ -B₁ -B3arrow_forward
- How many total electrons reside in MOs of p symmetry in the following molecule?arrow_forwardIn this chapter, you learned that a molecule that possesses a plane of symmetry must be achiral. It is possible, however, for a molecule to be achiral without possessing a plane of symmetry, such as in cases where the molecule possesses a point of symmetry. If a point of symmetry exists for a molecule, then each atom can be reflected through that point (rather than a plane) to arrive at an identical atom. This molecule, for example, is achiral, yet it possesses no plane of symmetry. Br CI CI Br (a) Convince yourself that the molecule has no plane of symmetry. (b) Draw the molecule's mirror image and show that the molecule and its mirror image are superimposable. (c) Where is the point of symmetry located?arrow_forwardWhich of the following possess an internal plane of symmetry? CI Br α (1) O I and III O III and IV O I only O All of them € (II) Br 'Br (III) (IV) + [1]arrow_forward
- Sketch the highest occupied molecular orbital (HOMO) of butadiene, sketch the lowest unoccupied molecular orbital (LUMO) of ethylene, and show that these orbitals have the correct symmetry for cycloaddition.arrow_forwardPrepare a representation flowchart for trans- N2F2, which has C2h symmetry.arrow_forward2. 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.arrow_forward
