Group# 2 Experiment No. 1 ------------------------------------------------- MELTING POINT AND BOILING POINT OF ORGANIC COMPOUNDS ------------------------------------------------- ABSTRACT The melting point (MP) and the boiling point (BP) are probably the most widely used physical constant in the field of science. Determining the boiling point and the melting point of a compound helps you to characterize

CLASSIFICATION TESTS FOR ORGANIC HALIDES James Anand L. Regala‚ Sabrina Nicolle G. Sarte‚ Ann Michelle Siao‚ Michael Sibulo‚ Victoria Tan Group 8 2C Pharmacy Organic Chemistry Laboratory ABSTRACT This experiment is done to classify organic halides. Most organic halides are synthetic and are not flammable. One way to classify organic halides is by classifying its -carbon atom as primary‚ secondary or tertiary. If the -carbon is attached to one R group‚ it is then primary. If the -carbon is

layer‚ then it is the organic layer. Tube 1 (water and n-butyl chloride)‚ after adding couple droplets of water‚ the water seems to dissolved at the bottom layer. This make sense because the density of water is 1000 kg/m3 is more dense than n-butyl chloride (880 kg/m3) and so we can say that water would be the bottom layer that’s why when water droplets was added in‚ the water dissolved at the bottom layer. Tube number 2 (water and n-butyl bromide)‚ after adding few drops of water‚ the bottom layer

Peptide synthesis – chemistry and modifications Peptides and proteins exhibit the largest structural and functional variation of all classes of biologically active macromolecules. Biological functions as diverse as sexual maturation and reproduction‚ enzyme inhibition‚ blood pressure regulation‚ glucose metabolism‚ thermal control‚ analgesia and learning and memory are now thought to be regulated by peptides.

allows the separation of it from the aqueous layer using a separatory funnel. The alkyl halide‚ then‚ were purified by a simple distillation apparatus using boiling point differences between the pure tert-butyl chloride and not. In this experiment‚ tert-butyl chloride is synthesized from tert-butyl alcohol. Introduction Alkyl Halides (also known as halogenoalkanes or haloalkanes) are a group of chemical compounds derived from alkanes containing one or more halogens. They are a subset of the general

Reactions: Procedure: 1. Measure 120 mg of 1‚4-dimethoxybenzene‚ 0.4 mL acetic acid‚ and 0.2 mL t-butyl alcohol 2. In a 10X100 mm reaction tube‚ dissolve the120 mg of 1‚4-dimethoxybenzene in the 0.4 mL of acetic acid. 3. Gently warm the solution within the reaction tube‚ it may be necessary to agitate the solution with a glass stirring rod and add the 0.2 mL of t-butyl alcohol 4. Cool the solution in an ice bath‚ once the solution is sufficiently cooled‚ place the reaction tube
