1-

CH3CH2OH in presence of conc. H2SO4 at 170°C gives out C2H4 (ethene) and water. H2SO4 acts as dehydrating agent.

2

CH3COOH and C2H5OH in presence of conc. H2SO4 gives CH3COOC2H5 amd water. Here ethanol and ethanoic acid react to form ethyl ethanoate, an ester.

3

CH3CH2OHin presence of alk. KMnO4 which is an oxidizing agent gives CH3COOH .

4

CH3CH2OH and Na gives sodium ethoxide CH3CH2ONa and H2.

5

Ch4 and 2O2 give Co2 and 2 h2o

CH3-C-CH-CH₂-OH C=CH₂​ A compound X (C₃H₆O) reacts with sodium to release a gas. On oxidation, it forms Y (C₃H₆O₂), which reacts with ethanol to form an ester Z (C₅H₁₀O₂) ha … ving a fruity smell. Another compound P (C₂H₄O₂) reacts with X to give Q (C₅H₁₀O₂), also an ester. Z and Q on hydrolysis give back their respective acids and alcohols. If X, Y, Z, P, and Q are all placed in separate test tubes, a student performs the following reactions: Tube 1: Add Na → gas is released Tube 2: Add Na → no gas Tube 3: Add Na → no gas Tube 4: Add water → conducts electricity Tube 5: Add water → does not conduct electricity Then the student arranges the compounds in increasing order of boiling points and mistakenly mixes Z and Q in an acid hydrolysis reaction, expecting only X and P to form. Questions: (a) Identify X, Y, Z, P, Q using IUPAC names and functional groups. (b) Write all possible chemical reactions including: Sodium reactions Esterifications Oxidation reactions Hydrolysis reactions (c) Predict the observations for the 5 test tubes, explaining why conductivity or gas is produced. (d) Correct the order of increasing boiling points. Justify chemically. (e) Predict the products if Z + Q undergo hydrolysis together. Explain why the student’s expectation is wrong. (f) Explain the differences in chemical reactivity between acids, alcohols, and esters observed here. 2O3 (g) ←→ 3O2 (g) At 300 K, ozone is 50% dissociated.
