Question

Identify Z in the sequence $ C{{H}_{3}}COON{{H}_{4}}\xrightarrow{\Delta }X\xrightarrow[\Delta ]{{{P}_{2}}{{O}_{5}}}Y\xrightarrow{{{H}_{2}}O/{{H}^{+}}}Z $

• A. $ C{{H}_{3}}C{{H}_{2}}CON{{H}_{2}} $
• B. $ C{{H}_{3}}CN $
• C. $ C{{H}_{3}}COOH $
• D. $ {{(C{{H}_{3}}CO)}_{2}}O $

Answer 1

The Correct Option is C

$ C{{H}_{3}}COON{{H}_{4}}\xrightarrow{\Delta }\underset{\begin{smallmatrix} \text{acetamide} \\ \,\,\,\,\,\,\,\,(X) \end{smallmatrix}}{\mathop{C{{H}_{3}}CON{{H}_{2}}}}\, $ $ \underset{(-{{H}_{2}}O)}{\mathop{\xrightarrow[\Delta ]{{{P}_{2}}{{O}_{5}}}}}\,\underset{\text{(Y)}}{\mathop{\underset{\text{methyl}\,\text{cyanide}}{\mathop{\text{C}{{\text{H}}_{\text{3}}}\text{CN}}}\,}}\,\xrightarrow{{{H}_{2}}O/{{H}^{+}}}\underset{(Z)}{\mathop{\underset{acetic\,acid}{\mathop{C{{H}_{3}}COOH}}\,}}\, $

Answer 2

Ans.

Acetic acid and ammonia combine to create the salt known as ammonium acetate. Applications for this ammonium salt include food preservation, pharmaceuticals, and chemical analysis. Ammonium Acetate, the salt's chemical name, is sometimes referred to as the spirit of Mindererus when it is present as a liquid. Ammonium acetate salt is the most efficient food acidity control. However, it is poisonous to the air and the surrounding environment.

Ammonium acetate is volatile at low pressure therefore it has been used to replace cell buffers with non-volatile salts that further help in the processing of various chemical samples. The chemical structure of the organic molecule ammonium acetate is commonly represented as follows:

Uses of Ammonium acetate

• Ammonium acetate is used widely. It's commonly used as a controlling agent for food acidity. It alters or regulates the alkalinity or acidity of foods. It's also commonly employed in the Knoevenagel condensation technique as a catalyst. The Borch reaction during organic synthesis uses the molecule as one of the greatest sources of ammonia.
• A protein-precipitating reagent is made by combining ammonium acetate with completely distilled water. 
• The substance may also be used as a buffer in ESI (electrospray ionization) mass spectrometry of molecules and proteins, as well as a mobile phase in HPLC (high-performance liquid chromatography). 
• Ammonium acetate is even more effective as a diuretic.
• Because ammonium acetate is unstable at low pressure, it is utilized to replace cell buffers with a variety of non-explosive salts in the processing of mass spectrometry samples.
