Why are covalent compounds generally poor conductors of electricity?
Name the following compound:
Name the gas evolved when ethanoic acid is added to sodium carbonate. How would you prove the presence of this gas?
1.Since, covalent compounds do not give rise to any ions in aqueous solutions, these compounds are generally poor conductors of electricity.
2.Since, the given compound contains propane as the parent chain and ketone as the functional group, the name of the given compound is (‘Propan’ + ‘ one’) propanone.
3.Ethanoic acid reacts with sodium carbonate to produce sodium ethanoate, carbon dioxide and water. The chemical equation involved in the reaction is:
Hence, carbon dioxide is the gas evolved when ethanoic acid is added to sodium carbonate.
When carbon dioxide gas is passed through lime water, it reacts with lime water to produce calcium carbonate a white precipitate which turns lime water (milky). This activity confirms the presence of carbon dioxide gas. The chemical equation involved in the reaction is:
