solution obtained in the conical flask. Fill 29.00mL of HCL in the burette. Use a pipette to transfer 10.00mL portion of the solution into a conical flask and drop 5 drops of methyl orange into it by using a dropper. Then‚ slowly open the mouth of the burette and allow HCL to flow into the conical flask containing Ca (OH)₂ and methyl orange as the indicator. Titrate the solution until the yellow colour of the solution turns into orange. Repeat the experiment for several times to get the average reading

using “Fmoc chemistry”. The first part of experiment was the synthesis of L-phenylalanine methyl ester hydrochloride. The methyl ester can be synthesised by reaction of thionyl chloride‚ SOCl2 and dry methanol with L-phenylalanine under reflux condition. The peptide bond was formed later in the experiment‚ where HBTU‚ DiPEA and a solution of Fmoc-Gly-OH in DMF were added to a solution of L-phenylalanine methyl ester hydrochloride in DMF. The product formed was the protected dipeptide‚ Fmoc-Gly-Phe-OMe

ADJIVON UNIT 1 INTRODUCTION Organic chemistry started as the chemistry of life‚ when that was thought to be different from the chemistry in the laboratory. Then it became the chemistry of carbon compounds‚ especially those found in coal. Now it is both. It is the chemistry of the compounds of carbon along with other elements

These are the only neurons that commonly regenerate. 3.Dan will not be able to taste normally if the olfactory epithelia are damaged‚ just as a cold reduces taste sensation. Input from the nasal receptors enhances flavor analysis. 4.Although debris did not enter his eyes during the explosion‚ there was intense light and heat from the explosion that

Carboxylic Acids and Their Derivatives Ma. Marielle M. Medura Prof. Emma Boncales Chem 23A (TTH 01:00-4:00 p.m) Carboxylic Acids and Their Derivatives I. Introduction Carboxylic acids is an organic compound that contains a carboxylic group(-COOH). Its general formula is R-C=OOH with R referring to the rest of the molecule such as H and C. They are directly attached to a carbonyl group and the interaction between them affects the reactions of each. The polarity of the O-H bond
