Check what you remember
Read the wording for your board, then hide it and explain Carbon-13 NMR and molecular symmetry in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Used to confirm the number of distinct carbon environments in the chosen structure, checking for symmetry so equivalent carbons are not counted as separate environments.
Equivalent carbons give one signal, so a symmetrical molecule shows fewer peaks than carbon atoms.
