Congratulational and Conformational Isomers | Stereochemistry Lec-1

Описание: 📘 Stereochemistry Lecture – 1 | Complete Basics Explained Step by Step

🔹 In this 1st lecture of Stereochemistry, we will cover:
1️⃣ Need of Stereochemistry (explained at 37:20 min timestamp)
2️⃣ Why lemon and orange — both made up of limonene — smell and taste different
3️⃣ What are enantiomers and how two enantiomers differ
4️⃣ How a bond is notated in organic molecules
5️⃣ Different types of bonds – Planar bond, Wedge bond, Dash bond
6️⃣ Difference between Sigma (σ) and Pi (π) bonds
7️⃣ What is Hybridization number and how to find it
8️⃣ How hybridization is determined in organic compounds
9️⃣ When hybridization number = 4 → atoms arranged in Tetrahedral geometry
🔟 Concept of Conformers (identical compounds)
🔹 Practice questions to identify which are conformers and which are not
🔹 Brief discussion on Isomers and their types
🔹 Difference between Structural and Stereoisomers (checked by connectivity)
🔹 Types of Stereoisomers:
  1) Geometrical Isomers
  2) Optical Isomers

🧠 How to check relationships between two molecules:
1️⃣ Check if they are mirror images or not
2️⃣ If not mirror images → Diastereomers
3️⃣ If mirror images → they can be Identical or Enantiomers
4️⃣ If superimposable mirror images → Identical
5️⃣ If non-superimposable mirror images → Enantiomers

🔹 Learn to distinguish Conformers vs Configurational isomers
🔹 Different representations of organic molecules:
  1) Fischer Projection
  2) Wedge–Dash Projection
  3) Sawhorse Projection
  4) Newman Projection

You will learn Interconversion of these 4 projections by using simplest LBDD Trick at 54:57 minutes.

🧩 Learn LBDD (Left, Back, Down, Dash) & RFUW (Right, Front, Up, Wedge) tricks
🔹 Left, back, and down bonds → represented by Dash bond
🔹 Apply these rules on propane molecule
🔹 Understand 4 different projections of propane
