of Acetanilide Introduction: Bromination of acetanilide to 4-bromoaniline was studied in this experiment. One of the most important mechanism with the reaction of aromatic compounds is the electrophilic aromatic substitution reactions(wade‚2013). The electrophilic aromatic substitution enable scientists to make substituted aromatic compounds. However‚ substitution groups affect the electrophilic substitution mechanism. A nitrogen atom attached to hydrogen is learned to be a powerful activating

Industry Visit – NeWater Plant An industry visit to Changi NeWater plant took place on 22nd February 2013 under the supervision of Amity faculty‚ Aditya Gupta. It was for a duration of 3 hours and our guide in NeWater was Sharul Mustafa. The guide gave a brief history about Singapore and the reasons why this plant was started. It was a very informative and enriching experience that helped us in understanding the value of nature and optimizing use of limited resources. As a souvenir a bottle of NeWater

of an electrophilic aromatic substitution reaction‚ in which a proton of an aromatic ring is replaced by a nitro group. Many aromatic substitution reactions are known to occur when an aromatic substrate is allowed to react with a suitable electrophilic reagent‚ and many other groups besides nitro may be introduced into the ring. Although the reaction produced a low yield at the end‚ the yield is calculated from the reaction and limiting reagent. Keywords: electrophilic aromatic substitution‚ nitration

after reacting with pyridinum tribromide in order to undergo electrophilic aromatic substitution. The melting point of the isolated products were measured against the standards in order to determine how strong of an ortho/para activator the compound was based on the product(s) and melting point obtained. Theory: Electrophilic aromatic substitution is an organic reaction that takes place when an atom that is bound to an aromatic ring is replaced by an electrophile. The electrophile replaces a hydrogen
