Carbon and Its Compounds

(a) How does ethanoic acid react with sodium hydrogencarbonate? Give equation of the reaction which takes palce. (b) Why are carbon and its compounds used as fuels for most aplications? (c ) Which of the two is better for washing clothes when the water is hard: soap or detergent? Give reason for your answer.

Which property is not exhibited by carbon in its compounds ?

Which oxidation state is not shown by carbon in its compounds?

STATEMENT-1 Oxidation state of carbon in its compound is always +4. STATEMENT-2 : An element can show variable oxidation numbers.

Carbon forms a large number of compounds because of its two unique properties formed many have long straight chains of carbon, branched chains of carbon or rings of carbon. In these compounds, carbon atoms may form single, double or triple covalent bonds. Compounds in which the carbon atoms are linked to each other by single bonds are called saturated carbon compounds whereas compounds having at least one carbon-carbon double or triple bond are called unsaturated carbon compounds. Compounds containing only carbon and hydrogen are known as hydrocarbons. Based on the above information, answer the following questions. i. Why does carbon form large number of compounds?
