Degrees of Unsaturation (IHD) — Fast Structural Constraint Tool: Mechanism + Exam Traps
The Index of Hydrogen Deficiency (IHD) tells you how many rings + π bonds are present. It’s the first move in almost every structure-determination problem.
Reaction: Degrees of Unsaturation (IHD) — Fast Structural Constraint Tool
What it does: The Index of Hydrogen Deficiency (IHD) tells you how many rings + π bonds are present. It’s the first move in almost every structure-determination problem.
Typical reagents: IHD calculation (analysis)
Key intermediate: Varies / context-dependent
Driving force: Relief of ring strain / formation of stronger bonds
