How will you test the chemical equation involved in the reaction of X with sodium. iii) Complete the following equation for X and identify Y. X overset("heat")(rarr)Y.

Answer»

Solution :i] The COMPOUND .X. is ETHANOL its chemical formula is `CH_3 - CH_2OH [C_2H_5OH]`
ii] Hydrogen gas is evolved when ethanol reacts with sodium. On bringing a burning MATCHSTICK near to the gas, it BURNS with a pop sound. The equation is 
`2C_2H_5OH + 2Na to 2 C_2H_5O^(-)Na^(+) + H_2 uarr`
iii] `underset(X)(CH_3CH_2OH)underset("HEAT")overset("Alk KMnO_4)(rarr) underset(Y)(CH_3COOH)`
The compound .Y. is ethanoic acid.
