into their original components. Mixtures of two miscible liquids with two different boiling points were separated. Therefore‚ it can be said that the two organic compounds are separated by exploiting the different boiling temperatures of the liquids. Both vaporization and condensation were used in this experiment. The two organic compounds used in this experiment were ethyl benzene and cyclohexane‚ which have the boiling point of 136°C and 80.74°C‚ respectively. This experiment resulted

Using LigandScout the pharmacophore features were predicted and 3D pharmacophore have been extracted via VMD software. A training set data was collected from literature and the proposed model was applied to the training set whereby validating and verifying their similar activity as that of the most active compounds. Therefore they could be

SYNTHESIS OF 1-PHENYLAZO-2-NAPHTHOL ABSTRACT Amines are compounds composed of nitrogen atoms bearing alkyl or aromatic compounds. Amines undergo interesting reactions‚ one of which is with the reaction with nitrous acid producing an azo dye. In this study‚ the experiment focused on synthesizing an observing the physical properties of Sudan-1. Sudan-1 is of the most common dyes found in waxes‚ oils and in some food ingredients specifically curry and chilli powder. Furthermore‚ this study aimed to

Thin Layer Chromatography (TLC) analysis was utilized to assess the polarity changes of the resulting compounds. Results indicated minimal alteration in CLA’s composition after iodine treatment‚ with both NaOH and IPA unexpectedly increasing the Rf values‚ suggesting reduced polarity. The simulation focused on understanding

When elements combine to produce a compound‚ each element is assigned an “apparent” charge. This apparent charge‚ the charge an atom would have if both electrons in each bond were assigned to the more electronegative element‚ may be positive or negative. It is called the oxidation number or state of the element in the compound. Oxidation numbers are very useful in keeping track of what happens to electrons when various elements combine to form compounds. By remembering a few generalizations
