Question

an organic compound with molecular formula C2 H4 O2 produces brisk effervescence on addition of sodium carbonate/bicarbonate
1. identify the organic compound
2. name the gas evolved
3. how will you test the gas evolved
4. write down the chemical equation for the above reaction
5. write down the two important uses for the above compound please answer

Answer 1

HEY MATE HERE IS THE ANSWER TO THE QUESTION.... ⚡⚡

▶️THE ORGANIC COMPOUND IS ETHANOIC ACID.
▶️GAS EVOLVED IS CO2️⃣.
▶️WE CAN TEST THE PRESENCE OF GAS BY ADDING CO2 WITH SLAKED LIME CA(OH)2️⃣
WHICH WILL GIVE CACO3️⃣ THAT IS MILKY IN NATURE.
▶️CA(OH)2️⃣ + CO2️⃣➡️➡️➡️ CACO3️⃣ + H2O
▶️EHANOIC ACID IS USED IN PHARMACEUTICAL AND ALSO USE TO MAKE ANTACIDS.
▶️ITS USED TO MAKE PLASTICS AND PVC PIPE ALSO.

Answer 2

1)ethanoic acid.

2)co2

3)by passing co2 in lime water, it turns milky

4)Reaction with sodium carbonate

2CH3COOH+Na2CO3==== 2CH3COONa +co2 + H2O

Reaction with sodium bi carbonate

CH3COOH NaHCO3===CH3COONa + co2+h2o
