H R H OH H primary R R OH R R OH OH R secondary tertiary phenol Alcohols with the hydroxyl bound directly to an aromatic (benzene) ring are called phenols. Nomenclature of Alcohols (Normally any compound’s name which ends in –ol is an alcohol of some sort) IUPAC rules that: (1) Name the longest carbon chain bearing the –OH group. Drop the last –e from the alkane

formation of an alcohol group at 3460 wavenumbers and the presence of aromatic rings at 1600 and 1490 wavenumbers which confirms the successful formation of triphenylmethanol. Introduction: The Grignard reagent is an effective reducing agent that may be used to reduce a ketone to an alcohol. Generally‚ the Grignard reagent is represented by an alkyl- or aryl-magnesium halide. The nucleophilic Grignard reagent attacks an electrophilic carbon‚ which results in the formation of a carbon-carbon bond.

a proposed type of pain-killer. Panacetin is typically made up of sucrose‚ aspirin‚ and acetaminophen‚ but the third component in this experiment is unknown. The unknown component is suspected to be a chemical relative of acetaminophen‚ either acetanilide or phenacetin. Using techniques such as extraction‚ evaporation‚ and filtration‚ the three components will be isolated based on their solubilities and acid-base properties. The percent composition of Panacetin will also be deduced based on the masses

You should be able to figure out what’s relevant by reading the procedure. (3) Find and report the boiling points of the solvents you will be using for this experiment. (4) Outline the steps in the recrystallization of acetanilide. Recrystallization involves dissolving a solid in a solvent and crystallizing it again‚ taking

Analysis of Oxygen Bearing Organic Compounds James Matthew Jocson*‚ Gianvittorio Lanta‚ Chiqui Ann Llamado‚ Jeron Manaig College of Science Department of Biology University of Santo Tomas‚ Manila‚ Philippines Abstract Five oxygen-bearing organic compounds were given namely Methanol‚ 2-propanol‚ tert - butanol‚ formalin‚ and acetone. Different tests were done to each sample to differentiate their characteristics. These test were Dichromate test‚ Tollens Test‚ DNPH test‚ Iodoform Test‚ and Lucas

Nucleophilic Substitution Introduction: The purpose of this lab is to investigate how different factors affect the rate of SN1 and SN2 reactions. SN2 reactions proceed via a one step mechanism in which the incoming nucleophile attacks the electrophilic carbon center from the opposite side of the leaving group. This reaction mechanism implies that the stereochemistry of a chiral center will be inverted. SN1 reactions proceed via two steps‚ slow dissociation of the C-X bonds to form an intermediate

to be present in your sample of Panacetin (aspirin‚ acetanilide‚ and starch)‚ only starch is insoluble in the organic solvent dichloromethane (or methylene chloride)‚ CH2 Cl2. If a sample of Panacetin is dissolved as completely as possible in dichloromethane‚ the insoluble starch can be filtered out‚ leaving acetanilide and aspirin in solution. The purpose of this experiment is to extract the components of Panacetin. Although the acetanilide and aspirin are both quite insoluble in water at room
