It's not about memorizing the periodic table, it is memorizing the mapping from names to structures. So, for example, the name of a compound might be 2,3-Diphe

It's not about memorizing the periodic table, it is memorizing the mapping from names to structures. So, for example, the name of a compound might be 2,3-Diphenylbenzoyl 2,4,6-trimethylbenzoate. Here is what the compound's structure looks like: https://pubchem.ncbi.nlm.nih.gov/compound/2_3-Diphenylbenzoyl_-2_4_6-trimethylbenzoate https://pubchem.ncbi.nlm.nih.gov/compound/2_3-Diphenylbenzoy... That information is encoded in the name, but you have to memorize all the rules for the encoding to be able to translate it.
