The reagents used in this experiment are: copper nitrate‚ ethanol‚ ethanoic acid‚ diethyl ether‚ 5% HCl‚ concentrated sulphuric acid‚ litmus paper‚ acetic acid‚ sucrose‚ methylamine‚ benzoic acid‚ 5% NaOH‚ 15% HCl‚ butyl bromide‚ buteraldehyde‚ nitro phenol‚ propanone‚ 5% NaHCO3‚ and phenolphthalein. This experiment is quite simple but it requires proper handling of chemicals since the chemicals used are toxic. Moreover‚ this experiment requires proper observation especially the solubility test

experience. Alfred visited the USA‚ Sweden‚ Germany and France. In Paris he worked in a chemical laboratory with professor Pelouza. There he met an Italian chemist‚ Sebrer‚ who discovered nitro-glycerine. In 1863 Alfred and his family moved back to Stockholm. His father opened a new factory for producing nitro-glycerine in a small town nearby‚ called Helene-Borg. A year later the factory exploded. It was a big tragedy because many people were killed including Alfred’s younger brother Emil. His father

51%. The melting point of Crop 1 was found to be 110-115 °C‚ and Crop 2 was found to be 37-90 °C indicating impurity in both crops. TLC analysis shows a less polar compound in Crop 1 than in Crop 2. IR and NMR data provide proof of benzene with a nitro group is present in Crop 1. Introduction: In this experiment an electrophilic aromatic substitution is performed. This is done by having the benzene ring attacked by an electrophile creating a carbocation intermediate within the benzene ring that
