How will you convert I aniline into fluorobenzene II benzamide into Benzylamine?
Aniline can be converted to fluorobenzene by first converting it to diaazonium salt and then carrying out the Balz – Schiemann reaction . Then it is made to react with fluoro boric acid and on heating it gives fluorobenzene .
How do you make fluorobenzene?
For preparation of fluorobenzene or its derivatives, there are known a process including the Schiemann reaction comprising diazotizating aniline with sodium nitrite in borofluoric acid or hydro- fluoric acid and pyrolyzing the obtained diazonium salt, a halogen-exchange process comprising substi- tuting the chlorine …
How do you convert aniline to Cyanobenzene?
when aniline is treated with NaNo2 +HCl it form benzene diazonium chloride and then further treated with CaCN then gives finally cyanobenzene.
How will you convert aniline into Benzonitrile?
(a) Conversion of Aniline to benzonitrile: Aniline is converted to benzonitrile by diazotization reaction followed by Sandmeyer reaction.
How do you make Fluorobenzene from BDC?
when benzene diazonium chloride reacts with fluoroboric acid it forms benzene diazonium fluoroborate. When this is heated it forms Fluorobenzene. This is the only reaction to form Fluorobenzene. This reaction is known as Schiemann reaction.
How do you convert Fluorobenzene to benzene?
In this reaction aniline is to be treated with nitrous acid to form benzene diazonium chloride,which is further reacted with HBF₄ to form benzene diazonium fluorobarate. This is when heated,undergoes decomposition to give fluorobenzene.
How do you make Cyanobenzene?
Production. It is prepared by ammoxidation of toluene, that is its reaction with ammonia and oxygen (or air) at 400 to 450 °C (752 to 842 °F). In the laboratory it can be prepared by the dehydration of benzamide or by the Rosenmund–von Braun reaction using cuprous cyanide or NaCN/DMSO and bromobenzene.
How do you convert aniline to benzamide?
(i) Convert Aniline to Benzamide Diazotise aniline and and react with CO2 to form benzoic acid and prepare amide. Another easiest way is to prepare the acid chloride with (COCl)2 and then treat the mixture with NH3.
How is Benzonitrile converted to benzoic acid?
Benzonitrile is converted to benzoic acid by basic hydrolysis. When benzonitrile is heated with aqueous sodium hydroxide solution, it liberates ammonia gas and converts to sodium benzoate which on acidification gives benzoic acid.
How do you convert aniline to Iodobenzene?
To convert aniline to idobenzene, it is reacted with as catalyst. This leads to the formation of an intermediate compound called Benzenediazonium chloride. When Benzenediazonium chloride is made to chemically react in the presence of potassium iodide as catalyst leads to the formation of iodobenzene.
