otl301- Post 3

Herein, I would like to share 2-3 intended learning outcomes for an organic chemistry course that I teach. Then, I will show my plans/ learning activities aligned to those intended learning outcomes.

Learning Objectives

  1. Students will acquire new knowledge about the alkyl halides and how to identify different types of alky halides. Student will also be able to define nucleophiles and order 10 common nucleophiles based on their strength.
  2. Students will understand the nucleophilic substitution reactions and their two major mechanisms, namely SN2 and SN1 by solving the mechanism for two given practice reactions.
  3. Students will analyze the role of substrate, nucleophile, leaving group and solvent in each type of aforementioned mechanisms.

Materials Required:

  • Organic chemistry textbook
  • Powerpoint lecture slides
  • AV equipment
  • List of common nucleophiles (copies printed for the total number of students)
  • Quiz sheets
  • Extra practice question (homework)

Content/Teaching and Learning Strategies:

Introduction

  • Welcome/ general announcements
  • Review of the last classes (showing 3-4 slides, example molecules)
  • Hook to start class (an Industrial application)

 

Main content (input)

  • Lecture 1: Alkyl halides (introducing different types and what is important about them)
  • Checkpoint 1: writing 5 structures on board and ask student to identify alkyl halides
  • Lecture 2: Nucleophiles and their strength
  • Checkpoint 2: Order the nucleophiles based on their strength on the list provided
  • Lecture 3: SN2 and SN1 mechanism of nucleophilic substitution reaction
  • Video (showing how some bonds are dissociating and how new bonds are forming during the course of reaction on a reaction profile and how transition state looks like)
  • Lecture 4: Role of substrate, nucleophile, leaving groups and solvent
  • Checkpoint 3: asking students to assign the mechanism for a 3 given reactions

Conclusion (consolidation)

  • Review of materials
  • Ungraded Quiz (on materials just covered – 3 questions)
  • Resource and materials for extra reading
  • Practice questions
  • Information about next classes
