Worksheet: Symmetry Operations
In this worksheet, we will practice defining a symmetry operation and describing the effect of inversion, reflection, rotation, and rotoinversion symmetries.
Which of the following properties is not a prerequisite for symmetry elements within the same symmetry group?
- AAssociativity ()
- BIdentity (The symmetry element times its identity, , remains unchanged.)
- CContinuity (If a molecule contains an axis, then it also contains axes of , .)
- DInverses (There must be an inverse symmetry element that returns the molecule to its original state; .)
- EClosure (If and belong to the group, and , then also belongs to the group.)
