Identify A, B and C from the following: C 2 H 5 OH → PCl 5 A → KCN B → H 3 O + C .

Given equation is: C 2 H 5 OH → PCl 5 A → KCN B → H 3 O + C . When ethanol reacts with phosphorous pentachloride, ethyl chloride is formed. The reaction is: C 2 H 5 OH → PCl 5 C 2 H 5 Cl + POCl 3 + HCl - A . Ethyl chloride reacts with potassium cyanide to form ethyl cyanide. The reaction is: C 2 H 5 Cl + KCN → C 2 H 5 CN + KCl - B . Now finally, when ethyl cyanide undergoes hydrolysis, propanoic acid is formed. The reaction is: C 2 H 5 CN → hydrolysis H 3 O + C 2 H 5 COOH - C .

Complete the equation CH 3 COOH → ? ClCH 2 COOH → NH 3 Excess of ?

Given equation is CH 3 COOH → ? ClCH 2 COOH → NH 3 Excess of ? We know that acetic acid reacts with chlorine in the presence of red phosphorous to form chloroacetic acid. This reaction is known as Hell-Volhard-Zelinsky reaction. The equation is: CH 3 COOH → Cl 2 / P ClCH 2 - COOH - A Chloroacetic acid reacts with ammonia to form glycine and ammonium chloride. The reaction is: ClCH 2 COOH + 2 NH 3 → CH 2 NH 2 COOH + NH 4 Cl - B
