Hydrocarbons & HalidesHandwritten Notes
Alkanes, alkenes, alkynes, and haloalkanes form the backbone of every organic synthesis JEE and NEET ask. These handwritten notes by Paaras Sir cover preparation, addition, substitution, and elimination reactions — with the SN1/SN2/E1/E2 selectivity rules clearly compared.

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.
