1.	(i) Carbon atom does not form C^(4-) anion and C^(4+) cation. Why ? (ii) How can ethanol be converted into ethanoic acid?
Answer» Solution :Carbon can gain four clectrons. But it would be difficult for the NUCLEUS with six protons to hold on to ten clectrons, tlhat is lour EXTRA electrons. It can lose four electrons but it would require a large amount of energy to remove four electrons leaving belhind a carbon calion with SIX protons in its nucleus holding on to just two eleetrons. Alkaline potassium permangnate or acidified potassium dichromate is ADDED to ETHYL alcohol. When it is heated it oxidises to FOMR ethanoie acid. `CH_(3)- CH_(2)-OH underset("AciditK"_(2)Cr_(2)O_(7)+"Heat")overset("Basic KmnO4+Heat")rarr CH_(3)COOH`
