Subject___ CHEMISTRY Class__12TH Section_ B TOTAL STUDENTS - 46
3. Lesson/Unit Name_----
NUCLEOPHILIC SUBSTITUTION RACTION IN ALKYL HALIDES
UNIMOLECULAR NUCLEOPHILIC SUBSTITUTION RACTION AND BIMOLECULAR NUCLEOPHILIC
SUBSTITUTION RACTION.
4. No. of periods required_ 01 ----Duration From__ 35-40 MINUTES.
A. Learning Outcomes (Specific
to the lesson mapped with NCERT 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.
9.
Define and use correctly the terms SN2, and SN1,.
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 :
Critical thinking by constructing structure of product of SN and Elimination reaction
Collaboration by Listing and collection different type of reaction and sharing of information
●
Creativity.
●
Communication
Activities/Experiments/Hands-on-learning/Projects:
1 Study of product of elimination reaction and Nucleophilic substitution reaction( reactivity of alkyl halide with Nucleophilic reagent polar and non polar solvent )
2 construction of structure of intermediate state in unimolecular reaction by ball and stick method
F. Interdisciplinary linkage and infusion of Life Skills, Values, Gender Sensitivity and Environmental Awareness:
1sensing the environment hazards in disposal of alkyl halides
2 comparing the cost effectiveness of different type of ball and stick s
