Discuss the relative stabilities of various conformation of 1,3 dimethylcyclohexane
Answers
Relative stabilities and various conformation of 1,3 dimethylcyclohexane:
1)If we glance the conformation analysis of cis 1,3-dimethyl cyclohexane, both the e,e and a,a conformer posses a sigma( σ)plane.
2)And thus it's optically inactive; no doubt of resolution arises.
3)In a,a conformer there's 2 additional inelegant methane series interaction and thus the e, e conformer is additional inhabited.
4)Then the related formula is shown below.
5) Here Trans is less stable than cis isomer by 1.8 k cal / mol
6)In case of trans chemical compound, both the e,a and a,e conformer contains one additional graceless alkane interaction and therefore each conformer is equally inhabited.
7)however ring invertion itself produces an equivalent conformer associate degreed therefore it's an example of topomerisation.
The planner structure contains a C2 axis and therefore it's dissymmetric however puckered-up structure contain no part of symmetry and therefore it's uneven molecule
