- Which of the following is an incorrect statement: Isomers have the same molecular formula such as cyclohexane and 1-hexene. Conformational isomers are enantiomers or diastereomers, which can interconvert through rotations around bonds within molecules, which include anti and gauche butane. Stereoisomers have the same connectivity but different arrangement of their parts in space, which include enantiomers, diastereomer, and conformational isomers, which include cis and trans dichlorocyclobutane. O Structural or constitutional isomers are molecules of the same formula but different connectivity such as 1,1-dichlorocyclopropane and 1.2-dichlorocyclobutane.arrow_forwardRank the conformations of n-butane with reference to its potential energy from the most stable to the least stable.

- What is the chair of cis-1,4-dibromocyclohexane?arrow_forwardIt is easy to imagine a cyclohexane as a flat hexagon and a lot of the time we draw it that way. Looking at 1,3,5-triethylcyclohexane we cannot tell the stability of the molecule from looking at the flat 2D drawing.

Which of the following statements about conformations is FALSE?
