Competency Based Lesson / Unit Plan
1. Name of the Teacher : Designation: PGT Chemistry
2. Subject :-CHEMISTRY Class 12 Section …………………….
3. Lesson/Unit Name:- Haloalkanes and Haloarenes
4. No. of periods required :- 08 Duration From ….. / … / ……. to …/… / …….
A. Learning Outcomes): After studying this topic, students will be able to
1. Differentiate primary, secondary, and tertiary alkyl halides.
2. Write the general electron-pushing (arrow-pushing) mechanisms for SN1 and SN2 reactions.
3. Draw the potential energy diagrams for SN1 and SN2 reactions.
4. Predict the favoured reaction between SN1 and SN2 mechanisms for a given haloalkane based on the structures of haloalkane, the structures of Nucleophilic, leaving groups, and solvents.
5. Predict the major product(s), including the stereochemistry of Nucleophilic substitution reactions.
6. Use the existing experimental evidence to describe the basis of our current understanding of the mechanisms of nucleophilic substitution at sp3 carbon. Write chemical equations to outline the mechanism for a particular halide.
7. Predict (and explain) the effect of alkyl, vinyl and aryl substituents on nucleophilic substitution.
8. Given the identity of nucleophile, leaving group, substrate and solvent, predict whether elimination or substitution will predominate for a particular alkyl halide substrate.
B. Details of Pedagogical Strategies/Process (Art integrated /Sports integrated/ Story telling based/Toy based /Any other pedagogy):
1 Toy based process – ball and stick structure of primary secondary and tertiary halides
2 Art integrated activity :- structure of intermediate species in SN1 reaction
3 story based activity :- story of cause of different product formation in elimination reaction and Nucleophilic substitution reaction (Role of solvent and type of halides)
4 :- PREPARED PPT or PDF OF ELIMINATION REACTION ( art- integrated).
C. Topic of the lesson for presentation by the students (once in a week by rearranging classroom setting suitable for group work):
NUCLROPHILIC REACTION VERSUS ELIMINATION REACTION.
D. Name 21st Century Skills to be developed :
