1.	(i) How will you bring about following conversion? Write the concerned chemical equations: (a) Ethanol to Ethene (b) Ethanol to Ethanoic acid. (ii) Give one example with chemical equation for following reactions: (a) Substitution reaction (b) saponification (c) combustion reaction.
Answer» Solution :(i) (a) `underset("Ethanol")(CH_(3)CH_(2)OH)underset(4443K)overset(H_(2)SO_(4)(conc.))tounderset("Ethene")(CH_(2)=CH_(2))+H_(2)O` (B) `underset("Ethanol")(CH_(3)CH_(2)OH)underset(("OXIDATION"))overset(K_(2)Cr_(2)O_(7)//H_(2)SO_(4))tounderset("Ethanoic acid")(CH_(3)COOH)` (ii) (a) `underset("Methane")(CH_(4))+Cl_(2)underset("sun light")overset("DIFFUSED")toCH_(3)CL+HCl` (b) `underset("Ethylethanoate")(CH_(3)COOC_(2)H_(5))+NaOHtounderset("Sod. Ethanoate")(CH_(3)COONa)+underset("Ethanol")(C_(2)H_(5)OH)` (c) `underset("Ethene")(2C_(2)H_(4))+5O_(2)overset(heat)to4CO_(2)+2H_(2)O`.
