The basic idea of geometrical isomerism is the difference between the spatial arrangement of atoms/groups between two compounds which have same molecular formulae and connectivity. One way of judging GI is analysing the difference between the distances of groups. Cumulenes having an odd number of double bonds are capable of showing GI (granted that the two ...

Overall I agree with Alchimista's answer, though I think it might be quite complex to grasp, seeing the comments that followed it. If it helps, here's my down-to-earth version, which in fact covers chirality in general, not just cyclohexanes. The 'executive summary' of my answer would be: not only it is correct to use an 'unnatural' or 'high energy' ...

Operatively: A plane of symmetry in a 2-D projection of a cyclohexane is a sufficient condition. Alternatively, and lengthy, you conduct an analysis involving conformers but not limited to the flipping of the ring, that means you must let the chloromethyl rotate, in your example. In more details: The answer to your title question is YES providing that the ...

If you are specifying it as 1,2 dimethyl cyclohexane you cant make any structures but with a general formula of dimethyl cyclohexane, you can make a few structures. once you have named the compound completely, you can't really make any structural isomers of it since the name ensures that you can make only one compound out of what name you have been given, ...

My teacher said there is one structural isomer I think (hope) you are talking about stereo isomers (i.e. same Lewis structure, different substance). There are two ways of counting. Either you can ask "How many substances are stereo isomers of cis-1,2-dimethylcyclohexane?" Or you can ask "How many stereo isomers exist of 1,2-...

Nitrogen will always perform nitrogen inversion if it is not configurationally fixed due to steric or electronic reasons. Fixing the configuration sterically could be achieved, for example, by a polycyclic compound as in 1 below. Fixing the configuration electronically is exemplified by the amide 2 (note that the amide is achiral; the nitrogen is forced into ...
