WebSolution. The correct option is D Both (a) and (c) Conditions for geometrical isomers: 1) Free rotation must be restricted. 2) Both the terminals must be attached with different groups. 3) Terminals must not be in perpendicular planes. In option b, one of the terminal carbon is attached with same group thus it will not show geometrical isomerism. WebConformational isomers. chemical structure of methane. Methane (CH 4) is a molecule that is a perfect tetrahedron, and so it is commonly said that no isomerism is possible with methane. However, the carbon - hydrogen bonds of methane constantly vibrate and bend, so that on very short timescales an apparent isomerism can be said to exist. http://www.organicmystery.com/Hydrocarbons/alkene.php slow cooked pork hotpot
