Web1. Find all the symmetry elements in cyclohexane with a chair conformation (3 points) 2. What is the point group for the cyclohexane molecule with a chair conformation (1.5 point)? How about the cyclohexane molecule with a boat conformation (1.5 points)? This problem has been solved! The 6-vertex edge ring does not conform to the shape of a perfect hexagon. The conformation of a flat 2D planar hexagon has considerable angle strain because its bonds are not 109.5 degrees; the torsional strain would also be considerable because all of the bonds would be eclipsed bonds. Therefore, to reduce torsional strain, cyclohexane adopts a three-dimensional structure known as the chair conformation, which rapidly interconvert at room temperature via a process known as a chair … tiffany 50th birthday giftsWebCyclohexane chair conformation-D3d It has a C-3 axis perpendicular to the plane ;Three C-2 axis ;Three v planes b)Tetrachloroallene-D2d Three C-2 axis;two v planes c)SO42- ion is … View the full answer Transcribed image text: 4-6 Determine the point group for a.
