Chemistry - STEREO ISOMERISM Question with Solution | TestHub
What is meant by operators in terms of elements of symmetry ? What is order of symmetry operation ? Show the symmetry operators of boat form of cyclohexane.
Options:
Answer:
Solution:
Ans. The order of the symmetry operations of the boat form of cyclohexane is 4 : E, C2, σv and σv'.
Sol. If a structure of a molecule can be transformed into an identical or indistinguishable structure by a physical movement based on an element of symmetry, without breaking or deforming any part of the molecule, then that manipulation is a symmetry operation; the total number of such operations is the order of the symmetry group. Boat cyclohexane belongs to C2v: it has the identity E, one two-fold axis C2 passing through the midpoints of the two flagpole bonds, and two vertical mirror planes σv and σv' containing that axis. Order = 4.
