E1 and E2 Reactions: Kinetics, Reactivity, Carbocation, Rearrangement, Saytzeff’s Rule, and Evidence

E1 and E2 reactions

E1 and E2 Reactions Definition E1 (unimolecular) and E2 (bimolecular) are elimination reactions in organic chemistry. E1 occurs in two steps formation of a carbocation followed by proton loss and follows first-order kinetics, favored by weak bases and polar protic solvents. E2 is a one-step reaction where a strong base removes a proton as the … Read more

Stability of Alkenes: Factors Influencing Stability

Alkanes

Stability of Alkenes: Key Influencing Factors The stability of alkenes, which contain at least one carbon-carbon double bond (C=C), depends on several structural and electronic factors. 1. Substituent Effects (Degree of Substitution) Alkyl groups stabilize alkenes via hyperconjugation and the inductive effect, donating electron density to the double bond. More substituted alkenes are more stable: … Read more

Alkenes

Alkenes

Alkenes are unsaturated hydrocarbons characterized by the presence of at least one carbon-carbon double bond (C=C), giving them distinct properties and reactivity patterns compared to their saturated counterparts, the alkanes. Their general formula is CnH2n, indicating they have fewer hydrogen atoms relative to alkanes. This section delves into the nomenclature, physical and chemical properties, and … Read more

Alkanes

Alkanes Definition and Classification Alkanes, also known as paraffins, are the simplest class of hydrocarbons, consisting only of carbon (C) and hydrogen (H) atoms with single covalent bonds. The general formula for alkanes is CnH2n+2. Types of Alkanes Straight-chain (Normal) Alkanes: Carbon atoms connected in a linear sequence without branches. Denoted as “n-” (e.g., n-pentane). … Read more

IUPAC systems of nomenclature of organic compounds

IUPAC systems of nomenclature of organic compounds

IUPAC Systems (International Union of Pure and Applied Chemistry) has established a standardized system for naming organic compounds, ensuring clear and unambiguous communication among chemists. IUPAC system applies to open-chain (aliphatic) compounds, carbocyclic compounds, and compounds containing functional groups. Below is a concise overview of the IUPAC systems nomenclature system for organic compounds with up to … Read more
