Molecular symmetry
What Molecular symmetry means in Chemistry A-Level, as defined for OCR.
Definition of Molecular symmetry
Check what you remember
Read the wording for your board, then hide it and explain Molecular symmetry in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Symmetry such as a plane of symmetry can make two separate groups equivalent, so their hydrogens count as one environment.
