Frequently Asked Questions

Are SN1 vs SN2 selectivity rules covered?+

Yes. All four factors (substrate, nucleophile strength, leaving group, solvent) are tabulated with worked product predictions for primary, secondary, and tertiary substrates.

Do the notes include ozonolysis with worked examples?+

Yes — reductive and oxidative ozonolysis are both covered with structure-determination problems showing how to back-calculate the alkene from carbonyl products.

Is anti-periplanar geometry of E2 explained?+

Yes. The anti-periplanar requirement is derived with Newman projections, and the consequence for E2 selectivity in cyclohexyl halides is worked through.
