Organic chemistry

Organic chemistry asks you to remember families of molecules, mechanisms and selectivity rules. Lumi brings them back in a spiral so you recognise a mechanism the moment you see a molecule.

How to turn this subject into cards

Organise organic chemistry by functional group, alcohols, alkenes, haloalkanes, carbonyls. For each, a card set for naming, one for reactivity, and one per reaction with its reagents, conditions and product. The trap is learning isolated reactions when mechanisms are what connect them. Tie each reaction to the logic of electron movement. Lumi asks for the product, the reagent or the name of the rule, and re-asks what slips away. Cramming into one evening gave a more fragile result than spreading study out in a vocabulary experiment (Kornell, 2009). It helps you remember names, reactions, rules and conditions.

Organic chemistry · teach this card to Lumi

Alkanes are saturated hydrocarbons with the general formula CnH2n+2. An alcohol contains a hydroxyl group bonded to a carbon. An SN2 reaction happens in one step with inversion of configuration. Markovnikov’s rule says that in the addition of HX to an alkene, the hydrogen adds to the carbon that already has more hydrogens. A chiral carbon has four different substituents.

Lumi’s question

Alkanes are _____ hydrocarbons with the general formula CnH2n+2.

Spaced repetition, how long to wait between two reviewsSpacing beats massing. The best gap between two sessions depends on how far away the exam is, with the benchmarks from Cepeda’s 2008 study.Active recall, why quizzing yourself beats rereadingReading once then quizzing three times gave 61% of ideas recalled after a week, against 40% for rereading four times (Roediger, 2006).Does interleaving, or mixed practice, really help you study?Mixing exercise types instead of grouping them. What Rohrer and Taylor (2007) and the Dunlosky review (2013) show.
