Halogen Derivatives — Class 12 Maharashtra HSC Chemistry revision notes
A 9-page visual revision sheet for Halogen Derivatives, written for Class 12 Maharashtra HSC Chemistry. Formulas, diagrams and the traps that cost marks, laid out to be read the night before rather than the term before. Free, and it opens inside CapCompass.
What this Halogen Derivatives sheet covers
- Haloalkane vs Haloarene
- Haloalkane
- Haloarene
- Classifying Monohalogen Compounds
- Nomenclature
- Preparing Alkyl Halides from Alcohols
- halogen acid, reactivity order 3 deg > 2 deg > 1 deg alcohol; ZnCl_2 (Lucas reagent) needed for 1 deg/2 deg but not 3 deg
- phosphorus trihalide, PBr_3/PI_3 generated in situ from red P + Br_2/I_2
- PCl_5 on an alcohol
- thionyl chloride, byproducts are BOTH gases, so no separation needed: the preferred route for straight-chain 1 deg alcohols
- Other Preparation Routes
- Physical Properties
- Chirality and Optical Isomerism
- SN1 vs SN2 Mechanism
- SN1
- SN2
- Ambident Nucleophiles
- Factors Deciding SN1/SN2
- Reaction with Active Metals
- Reactions of Haloarenes
- Uses and Environmental Effects of Polyhalogen Compounds
- Ozone Depletion by CFCs
- UV light breaks the weakest bond in the CFC
- the chlorine atom destroys ozone catalytically, then regenerates
- Traps that cost marks
- Tricks that save time
How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans Chemistry chapter by chapter against your real exam dates and free hours, and when the plan reaches Halogen Derivatives the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
