How can ethanol and ethanoic acid be differentiated on the basis of their physical and chemical properties ?
Ethanol is a liquid at room temperature with a pleasant odour while ethanoic acid has vinegar-like smell. The melting point of ethanoic acid is $17\,^oC$. This is below room temperature and hence, it freezes during winters.
Ethanoic acid reacts with metal carbonates and metal hydrogencarbonates to form salt, water, and carbon dioxide gas while ethanol does not react with them.
Metal Carbonates $/$ Metal Hydrogencarbonates $+$ Carboxylic acid
$\downarrow $
Salt $+$ Water $+$ Carbon dioxide
For example,
$2 CH _{3} COOH + Na _{2} CO _{3} \longrightarrow 2 CH _{3} COONa + H _{2} O + CO _{2}$
Metal Carbonates $/$ Metal Hydrogencarbonates $+$ Alcohols
$\downarrow $
No reaction
For example,
$CH _{3} CH _{2} OH + Na _{2} CO _{3} \longrightarrow$ No reaction
Explain the formation of scum when hard water is treated with soap.
Ethane, with the molecular formula $C_2H_6$ has
What would be the electron dot structure of carbon dioxide which has the formula $CO _{2}$ ?
What are oxidising agents ?
Why are carbon and its compounds used as fuels for most applications ?
