(2marks) Using the Benedict’s regeant tests‚ once the blue reagent was added to the chocolate milk color‚ the color would change according to the sugar percentage. The chocolate milk would change from light green‚ to green/yellow‚ orange or from red to brown. A sample of the chocolate milk would change to a red color for the lipids present and also another sample of the chocolate milk would change to a deep purple once the Biuret’s reagent is added from the protein in the chocolate milk.

had four testing reagents (Lugol’s which tests for starch‚ Biuret tests for protien‚ Benedict’s that tests for reducing sugars‚ and Ninhydrin which detects amino acids) and four stock solutions at various concentrations (protein in the form of albumin‚ glucose for the sugars‚ amino acid through glycine and just basic starch). We tested each of these with our three unknowns (which were the three separate protein supplements). Mixing each individual supplements with all of our reagents and stock solutions

It is important to examine the understanding of physical laboratory by the candidate and ability to identify the apparatus which are permanently fixed in laboratory study room. The candidate should be able to distinguish between the apparatus and reagents and identify apparatus usually locked in special stores and not easily accessible for reasons such as being delicate. | 2) Interview Question: | What is the first thing you or your students do immediately you enter in a laboratory room and why

4. The protons on D show a singlet as the protons on both carbons are similar due to the symmetry of the ketal group‚ thus they would be considered equivalent and would not split each other. The possible impurities are caused by leftover starting reagent. The 1H NMR of the final product shows protons present on the aromatic rings seen as peaks at 6.5-8.5 ppm‚ due to the symmetry of the protons D‚ E‚ and F have similar electron environments despite being on separate rings (Figure 5).

Abstract – This multi-step synthesis uses aniline as the starting reagent to synthesize five compounds employing several reactions such as acetylation‚ diazo coupling‚ nitration‚ bromination‚ and hydrolysis. The isolated products were analyzed with TLC and spectral data that determined most products were pure while some had a few impurities indicated by GC‚ LC‚ and a wide melting point range was shown for products 2 and 3. The presence of water in product 2 and 7 was indicated by the IR. Acetanilide

acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heated water bath. The solution was cooled slowly in an ice bath as crystals form out. As the compound crystallizes from the solution‚ the limiting reagent Aniline and the percent yield of 96% was obtained. Introduction: This experiment involves four functional groups common in organic chemistry. The substrate (reactants) which are Aniline and Acetic anhydride are both liquids and one of the products

INTRODUCTION: Carbohydrates are the product that made up from carbon‚ hydrogen and oxygen. Carbohydrates are form by the combination of carbon dioxide and water molecules. The carbohydrates contain two specific functional group in it which is the hydroxyl groups and carbonyl groups.A reducing sugar is a type of sugar with is an aldehyde group.This means that sugar can act as a reducing agent.The procces of reducing sugar is isomerisation‚example of reducing sugar islactose
