\( \newcommand\) • • • • • • • • • • • Ozonolysis is a type of weak oxidative cleavage where we cleave alkenes (double bonds) into either ketones, aldehydes or carboxylic acid using ozone. The History of Ozonolysis Ozonolysis, or “oxidative cleavage” originated in the 1800’s with its inventor, Christian Friedrich Schönbein. The reaction also is attributed to Carl Dietrich Harries, therefore you may hear this reaction termed “Harries ozonolysis”. You may be thinking, “Umm... Why do I need to know this?”. The answer is, well you don’t! (But in case you were wondering, now you know & can tell your friends). Ozone Structure It is in simplest terms using ozone, or O 3 (the structure is shown above with correct formal charges) to cleave carbon-carbon double bonds (C=C) to produce various carbonyls. Pathways 1. Aldehydes (CHO), and ketones (CH 3COCH 3) can be formed through reductive workup. This refers to what is shown under the arrow below. Me 2S is also DMS and stands for Ozonolysis Retrosynthesis Now I’m sure you’re wondering, which structure was our starting material? For that answer scroll down just a bit, but first try to draw it out! 2. Carboxylic acid (COOH, CO 2H) can also be formed as well except it is through an oxidative workup step instead. H 2O 2 (hydrogen peroxide) is the reagent to look out for because as seen below it turns: - Ends of alkenes with 1 –H ≠ Aldehydes but Carboxylic Acids instead Ozonolysis with Oxidative Workup Answer from above: Di-substituted A...

\( \newcommand\) • Pyridinium chlorochromate (PCC) is a milder version of PCC oxidizes alcohols one rung up the oxidation ladder, from primary alcohols to aldehydes and from secondary alcohols to ketones. In contrast to chromic acid, PCC will not oxidize aldehydes to carboxylic acids. Similar to or the same as: \(CrO_3\) and pyridine (the Collins reagent) will also oxidize primary alcohols to aldehydes. Here are two examples of PCC in action. • If you add one equivalent of PCC to either of these alcohols, the oxidized version will be produced. The byproducts (featured in grey) are Cr(IV) as well as pyridinium hydrochloride. • One has to be careful with the amount of water present in the reaction. If water is present, it can add to the aldehyde to create the hydrate, which could be further oxidized by a second equivalent of PCC if it is present. This is not a concern with ketones because there is no H directly bonded to C. How does it work? Oxidation reactions of this sort are actually a type of elimination reaction. The reaction starts with a carbon-oxygen single bond and results in a carbon-oxygen double bond. The elimination reaction can occur because of the good leaving group on the oxygen, namely the chromium, which will be displaced when the neighboring C-H bond is broken with a base. The first step is attack of oxygen on the chromium to form the Cr-O bond. Secondly, a proton on the (now positive) OH is transferred to one of the oxygens of the chromium, possibly throu...

We discuss the molecular geometry, hybridization, bond angle , octet rule, dipole moment and other related facts in detail and some frequently asked questions. Dichloromethane ,mainly called as methylene chloride, is a polar organic solvent that is mostly used in various type of chemical research and manufacturing purpose also. It is a highly volatile liquid. Molar mass of DCM is 84.93gm/mol. Melting point and boiling point of CH 2Cl 2 are -96.7 and 39.6 degree celcius respectively. In this article the lewis structure of CH2Cl2 and other detailed facts are discussed briefly. CH2Cl2 lewis structure molecular geometry Molecular geometry of any molecule can be determined by using VSEPR (Valence Shell Electron Pair Repulsion) Theory.. The main agenda to determine the structure of any compound using this VSEPR theory that the atoms or substituents around the central atom will adopt such an arrangement that the repulsion between the valence shell electrons will be minimum. Analysing VSEPR theory it can be concluded that CH 2Cl 2 possesses a tetrahedral like molecular geometry (Methane like structure) as the carbon atom ( central atom) have two different types of atoms ( two hydrogen and two chlorine) around it.

Among these 6 electrons there are 2 electrons in its 1s orbital and 2 electrons in its 2s orbital a...

Dichloromethane or methylene chloride, with the chemical formula CH2Cl2, is a colorless, volatile liquid with a boiling point of 39.6 °C. and a melting point of -96.7 °C. It is widely used as a solvent in chemistry laboratories. It is polar because of the presence of two chloro groups but is not miscible with water; however, it does show miscibility with various organic solvents such as chloroform, carbon tetrachloride, hexane, benzene, ethyl acetate, and alcohols. The preparation of CH2Cl2 involves a high-temperature treatment of methane or chloromethane with chlorine gas. CH2Cl2 Lewis Structure The Lewis theory of chemical bonding—although quite primitive and the most limited theory on electronic structure—does help one to determine how valence electrons are arranged around the constituent atoms in a molecule. The purpose of this theory is to help visualize the chemical bonding of atoms in molecules. Electrons are represented as dots, and each pair of bonding electrons between two atoms is shown as a line. The structures drawn using this theory are termed Lewis (dot) structures. Please note that several atoms follow the octet rule, i.e., they tend to achieve eight electrons in their valence shell through chemical bonding; this is reflected in the Lewis structure of the molecule. Hydrogen, however, does tend towards a duplet, not octet, because it has only one electron in its K shell, and thus needs only one more to achieve the maximum capacity of the K shell. i. The atom...
