Chiral center cyclohexane
WebNov 15, 2024 · 1 Answer. The functional groups are on the same carbon, so either configuration can be rotated into the other. If the functional groups were on different carbons, then depending on their relative locations the molecule could be chiral. Second sentence is not correct. Cis and trans 1-ethyl-4-methycyclohexane are achiral. WebSince both carbons attached to the bromine atoms are chirality centers, by the formula #(isomers)=2^(#centers) given in an earlier video, wouldn't there be four isomers for the 1,2-dibromohexane ring? ... We start out with our cyclohexane ring and you can see at this carbon our Bromine is going down in space so that must be a dash, so there's ...
