Cis trans chair conformers
WebThe chair is the most stable conformation of cyclohexane, as the ring strain is minimized in it. These different conformations of a cycloalkane are known as conformational isomers or conformers. Conformers are formed by the continuous rotation of bonds in a cyclic structure without bond breaking. WebDrawing Conformers of Cyclohexanes and Conformational Analysis MAH@ACP 4.
