Epoxidation Reactions Lab Report 2 Abstract An oxygen atom is transferred from a peroxy acid to the carbon=carbon double bond thus forming an epoxide. Scheme 1. Oxone Epoxidation. Scheme 2. mCPBA Epoxidation. The percent yield for the Oxone epoxidation reaction was 65% yield and the mCPBA epoxidation reaction was 70% yield. Oxone is the greener alternative because using mCPBA is twice as expensive as Oxone and leaves behind the epoxide plus m-chlorobenzoic acid while Oxone creates non-toxic

Coco commissioned Russian perfumer Ernest Beaux to create what would become the ultimate Chanel masterpiece and greatest classic perfume of all time—an abstract floral overdosed and overpowered with sparkling yet heavy synthetic chemicals called aldehydes. Chanel No. 5 was ahead of its time as a composition. It was impactful‚ long lasting‚ unique and libertarian in its essence. The juice’s signature hasn’t changed since its creation‚ yet its attributes have evolved to become aspirational in a more

Amines are essential for the building blocks of life; they are a key component in the formation of amino acids‚ proteins‚ and nucleic acids. Amines contain nitrogen that has one lone pair; this enables it to form 3 covalent bonds with other atoms‚ all while staying neutral. Due to an amines basicity‚ reaction with an acid is very easy and forms a positively charged ammonium ion. As well as being a strong base‚ amines are also quite good nucleophiles. When the nitrogen is directly attached to one

Macromolecules are molecules that are large and essential for life. They consist of carbohydrates‚ nucleic acids‚ proteins‚ and lipids. Carbohydrates are molecules that are composed of monosaccharaides. Carbohydrates include cellulose‚ starches‚ and sugars. Two tests may be used to determine the presence of the carbohydrates. Those tests are the Benedict’s test and Lugol’s Iodine Test. Proteins are another category of macromolecules. The protein is a type of macromolecule that carry out many processes

INTRODUCTION Macromolecules are highly important organized organic molecules that are found within living cells. These biological molecules help the body execute precise important tasks. There are four types of macromolecules: carbohydrates‚ lipids‚ proteins and nucleic acids. (Karp‚ 2010) This specific experiment showcased the identification of different macromolecules using three different testing methods. Carbohydrates‚ sugar molecules‚ are known as “fast fuel” in the body‚ and they contain

Pre-lab 1: Identifying Carbohydrates Abstract The point of this lab is to determine if a substance contains carbohydrates such as a reducing sugar and/or polysaccharides. This will be done by using Benedict’s reagent and Iodine stain tests. Benedict’s reagent will react to reducing substances in the solution by oxidizing it and changing the structure of the reducing sugar to form a colored precipitate. The color of this precipitate can be used to determine the concentration of reducing sugars in

as well as above other reactions of enolates has serious limitations to be overcome. In these reactions‚ a strong base NaOH is needed to transform the carbonyl compounds into their anion forms. Generally‚ the carbonyl compounds such as ketone and aldehyde have high pKa values (pKa ~ 20) [1]. It is difficult to make their − anion forms of carbonyl compounds by removing the hydrogens on the α-carbons because of their weakly acidic characteristics. Therefore‚ the product yields of acylation‚ alkylation

Distillation Alcoholic distillation is basically the process of separation the more volatile component‚ alcohol‚ from the less volatile component‚ water‚ from a water/alcohol solution‚ by heating the solution and condensing and collecting the alcohol rich vapours released‚ as a high alcohol strength liquid (spirit). The starting material for most distillations‚ such as wine for brandy and beer for whisky‚ are usually weak alcoholic solutions (5%-7% v/v ethanol) This seems counter intuitive
