Nucleophilic Addition Reactions

Curriculum Module NAR

Nucleophilic Addition Reactions

Aldehydes, Ketones, Carbonyl Reactivity, Cyanohydrins, Grignard & Acetals

149 SlidesFull Master Compendium

Core Mechanistic Pathways

Reactivity gradient: Formaldehyde > Aldehyde > Ketone
Hydration and acetal/ketal cyclic protecting groups
Cyanohydrin formation & subsequent hydrolyses
Grignard & organolithium nucleophilic attack
Addition of ammonia derivatives (imines, oximes, hydrazones, 2,4-DNP)
Sodium bisulfite addition & separation of carbonyls

Key Reagents & Conditions

HCN / KCNR-MgX in dry etherROH / dry HClNH₂-G / mild acid (pH 4.5)NaHSO₃

Stereochemical Dynamics

Attack on prochiral sp² carbonyl faces (Re/Si face selectivity), Cram’s Rule and Felkin-Anh model basics.

Module Summary & Study Guidance

The master deck for carbonyl nucleophilic additions. Features exhaustive kinetic comparisons, steric hindrance analysis, reversible vs irreversible pathways, and step-by-step orbital interactions.

Exam Orientation: JEE Advanced Highest Yield · Aldehydes & Ketones core. All materials are embedded directly on Chem-Mantra with online presentation and secure reference reading modes.
