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

Since I was eight years old my family has always had a boat. From fishing‚ tubing‚ hunting and just cruising we did it all. My Dad’s first boat‚ Nitro 189 Fish and Ski‚ was the light of my life. Since the day he got it I was his first mate. Helping him with everything cleaning‚ stocking and repairing. I took great interest and pride into that boat‚ more than my dad at times‚ which motivated me to get my boaters license and learned how to work on marine engines before I was 14. Every year we go

Water ecology‚ which studies on the interaction between of biotic and abiotic factors to the growth of organism in water‚ is too important in order to keep the ecosystem balance. In our study‚ we focused on how the fertilize (nitro‚ phosphorus) effects on the populations of water organisms. Euglena is the mixotrophic which could synthesis energy from photosynthesis‚ but also could consume the food to make energy (Robert.et al‚ 2012). From the trophic characteristic of Euglena

benzoate was treated with concentrated Nitric and Sulfuric acid to yield methyl m-nitrobenzoate. The product was then isolated and recrystallized using methanol. This reaction is an example of an electrophilic aromatic substitution reaction‚ in which the nitro group replaces a proton of the aromatic ring. Following recrystallization‚ melting point and infrared were used to identify and characterize the product of the reaction. Purpose: The purpose of this experiment is to synthesize methyl nitrobenzoate
