As used in subsection C of Section 2-204 of this title, "isomer" means the optical, positional or geometric isomer. As used in paragraph 4 of subsection A of ... WebIn terms of definition, you are correct about conformational isomers and the rotation around the sigma bond. However, since the molecules drawn are the same, they are not "different based on the rotation of the sigma bond between the carbon and the methyl substituent," at least not based on what's drawn. In fact, we don't have enough ...
