1.	An organic compound 'P' is a constituent of wine. 'P' on reacting with acidified K_(2)Cr_(2)O_(7) forms another compound 'Q'. When a piece of sodium is added to 'Q' a gas 'R' evolves which burns with a pop sound. Identify P, Q and R and write the chemical equations of the reactions involved.
Answer» Solution :P-Ethanol, Q-Ethanoic acid, R-Hydrogen `CH_(2)CH_(2)OH overset("Acidified ")to K_(2)Cr_(2)O_(2) +CH_(3)COOH` `2CH_(3)COOH+ 2NA RIGHTARROW 2CH_(3)COONA+ H_(2)`
