The SN1 Reaction Mechanism and SN1 Practice Problems
The fast reaction of the carbocation with the nucleophile is the driving force of the S N 1 reaction since it pulls the equilibrium to the right according to the Le Châtelier’s principle. S N 1 – A Two-Step Mechanism. Let’s break down all the steps in the following S N 1 reaction by looking at the energy diagram:. Step  Breaking the C – LG bond. In this rate-determining step, a
Pinacol rearrangement - Wikipedia
The pinacol–pinacolone rearrangement is a method for converting a 1,2-diol to a carbonyl compound in organic chemistry 1,2-rearrangement takes place under acidic conditions. The name of the rearrangement reaction comes from the rearrangement of pinacol to pinacolone. This reaction was first described by Wilhelm Rudolph Fittig in 1860 of the famed Fittig reaction
Newman projection - Wikipedia
A Newman projection, useful in alkane stereochemistry, visualizes the conformation of a chemical bond from front to back, with the front atom represented by a dot and the back atom as a circle. The front atom is called proximal, while the back atom is called distal type of representation clearly illustrates the specific dihedral angle between the proximal and distal
IUPAC Nomenclature Practice Problems - Chemistry Steps
This is a set of practice problems on naming organic compounds. The examples cover the nomenclature of alkanes, bicyclic compounds, alkenes, alkynes, alcohols, alkyl halides, aromatic compounds, aldehydes and ketones, amines, ethers, and carboxylic acid derivatives such as nitriles, esters and amides of the examples are also compounds with multiple
organic problems - Michigan State University
4 Which of the following must be true for an optically active compound? A) the molecular configuration is achiral B) the molecular configuration is chiral C) the compound is a racemic mixture of enantiomers D) the molecular configuration must have two or more stereogenic centers
Organic chemistry | Science | Khan Academy
Carbon can form covalent bonds with itself and other elements to create a mind-boggling array of structures. In organic chemistry, we will learn about the reactions chemists use to synthesize crazy carbon based structures, as well as the analytical methods to characterize them.
IR Spectroscopy: 4 Practice Problems - Master Organic Chemistry
Nov 29, 2016IR Spectroscopy Practice Problems. By itself, Infrared (IR) spectroscopy isn’t a great technique for solving the structure of an unknown moleculever, we’ve seen that IR spectroscopy can a great technique for identifying certain functional groups in an unknown molecule – especially functional groups containing OH or C=O. For instance, in an earlier post

22: The D and L Notation - Chemistry LibreTexts
Problems: Contributors; The stereochemistry of carbohydrates is generally described by using D/L notation, as opposed to the modern R/S (Cahn-Prelog-Ingold) method. Background of D/L notation. The d/l system (named after Latin dexter and laevus, right and left) names molecules by relating them to the molecule glyceraldehyde.
