Two organic compounds 'A' and 'B' react ...

Two organic compounds 'A' and 'B' react with sodium metal and both produce the same gas 'X', but with sodium hydrogen carbonate only compound B reacts to give a gas 'Y'. Identify 'A'. 'B', 'X' and 'Y'.

A

A = Ethylene, B = Ehyl alochol,
X - Carbon dioxide, Y - Hydrogen.

B

A = Ethyl alcol, B = Acertic acid,
X = Hydrogen, Y = Carbon diocxide.

C

A = Hydrogen, Y = Carbon dioxide.
X = Hydrogen, Y = Carbon dioxide.

D

X = Carbon dioxide, Y = Hydrogen.

The correct Answer is:
To solve the problem, we need to identify the organic compounds 'A' and 'B', as well as the gases 'X' and 'Y' produced in the reactions described. ### Step-by-Step Solution: 1. **Understanding the Reactions**: - Both compounds 'A' and 'B' react with sodium metal to produce the same gas 'X'. - Only compound 'B' reacts with sodium hydrogen carbonate to produce gas 'Y'. 2. **Identifying Compound 'B'**: - Since only compound 'B' reacts with sodium hydrogen carbonate (NaHCO₃), it must be an acid. Sodium hydrogen carbonate reacts with acids to produce carbon dioxide (CO₂). - A common organic acid is acetic acid (CH₃COOH). 3. **Reaction of Compound 'B' with Sodium**: - When acetic acid reacts with sodium metal, it produces sodium acetate (CH₃COONa) and hydrogen gas (H₂). - The reaction can be represented as: \[ \text{CH}_3\text{COOH} + \text{Na} \rightarrow \text{CH}_3\text{COONa} + \text{H}_2 \uparrow \] - Therefore, gas 'X' produced in this reaction is hydrogen gas (H₂). 4. **Reaction of Compound 'B' with Sodium Hydrogen Carbonate**: - The reaction of acetic acid with sodium hydrogen carbonate produces sodium acetate, carbon dioxide (CO₂), and water (H₂O): \[ \text{CH}_3\text{COOH} + \text{NaHCO}_3 \rightarrow \text{CH}_3\text{COONa} + \text{CO}_2 \uparrow + \text{H}_2\text{O} \] - Thus, gas 'Y' produced in this reaction is carbon dioxide (CO₂). 5. **Identifying Compound 'A'**: - Since both compounds 'A' and 'B' produce the same gas 'X' (H₂) when reacting with sodium, and 'A' must not react with sodium hydrogen carbonate, 'A' is likely an alcohol. - A common alcohol is ethyl alcohol (ethanol, C₂H₅OH). - The reaction of ethanol with sodium metal also produces sodium ethoxide (C₂H₅ONa) and hydrogen gas (H₂): \[ \text{C}_2\text{H}_5\text{OH} + \text{Na} \rightarrow \text{C}_2\text{H}_5\text{ONa} + \text{H}_2 \uparrow \] 6. **Final Identification**: - Therefore, we can summarize: - Compound 'A' is Ethyl Alcohol (C₂H₅OH). - Compound 'B' is Acetic Acid (CH₃COOH). - Gas 'X' is Hydrogen (H₂). - Gas 'Y' is Carbon Dioxide (CO₂). ### Summary: - **A**: Ethyl Alcohol (C₂H₅OH) - **B**: Acetic Acid (CH₃COOH) - **X**: Hydrogen (H₂) - **Y**: Carbon Dioxide (CO₂)
