EXPERIMENT 15 ANILINE PART B Flashcards
chemicals used in the NH2 group on substitution in the benzene ring?
Aniline
Bromine
water
what were the observable results on the test of Amino group substitution of benzene ring?
Presence of white ppt which was the 2,4,6 - tribromoaniline
Presence of orange globules - Br2H2O
Presence of a pale yellow solution
by product of the Amino group on substitution test?
Amino (C6H5NH2) + 3Br —-> 2,4,6 triboromoaniline + 3HBr (Hydrogen Bromine)
what was the white precipitate and orange globules present in the experiment of the Effect of Amino Group on substitution in the Benzene Ring?
the white ptt was the 2,4,6-tribromoaniline
Orange globules - Br2H2O
what was the test when the byproduct of the mixture was anilinium chloride?
Basicity , Salt test,
in the diazotization test what happened?
it created a byproduct of a Benzenediazonium chloride (C6H5NH2 =- Cl) + Sodium chloride (NaCl) + Nitric acid
it created a colorless solution or pale red solution
what was the catalyst in the diazotization test?
presence of cold temperature 0-5 degrees celcius
what was the catalyst of the effect of NH2 group substitution in the benzene ring?
none
what was the byproduct of the diazotization test?
the byproduct was the benzenediazonium chloride (C6H5NH2 =-Cl) + Sodium Chloride (NaCl) + Nitric Acid (HNO3)
what happened in the formation of phenol?
the benezenediazonium chloride went from a colorless solution to a red solution due to the presence of heat.
It emitted a paste like smell which was the phenol
The chemicals used were only benzenediazonium chloride with a catalyst of heat
what created the presence of paste like smell in the formation of phenol?
presence of phenol (C6H5OH)
what were the gas evolved in the formation of phenol?
phenol and nitrogen
the chemical formula for the formation of phenol?
Water + Benzene diazonium chloride (C6H5=-NCl) –(Heat)—> Phenol (C6H5OH) + Nitrogen (N2) + Hydrochloric Acid (HCl)
what was the chemical equation in the effect of NH2 Group on Substitution in the benzene ring?
Anilinium (C6H5NH2) + Bromine (3Br) —-> 2,4,6 tribromoaniline + 3HBr
chemical equation for the formation of basicity?
Anilinium (C6H5NH2) + Water (H2O) —> Anilinium Hydroxide (C6H5OH)
Anilinium hydroxide (C6H5OH) + Ferric Chloride (FeCl3) —> Anilinium Chloride + Ferric Hydroxide (Fe(OH)3)
