Open computer molecular models for dimethyl ether, dimethylacetylene, and cis-1,2- ichloro-1,2-difluoroethene from the 3D Molecular Models section of the book's website. By interpreting the computer molecular model for each one, draw
(a) A dash formula,
(b) A Bond-line formula, and
(c) A three-dimensional dashed-wedge formula. Draw the models in whatever perspective is most convenient- generally the perspective in which the most atoms in the chain of a molecule can be in the plane of the paper.
