(a) A compound X with molecular formula, C2H4 burns with a sooty flame. It decolourises
bromine water. Identify X. Will it dissolve in water or not? Will it conduct electricity in
aqueous solution?
(b) An organic compound X is an essential constituent of wine and beer, which is responsible
for intoxication caused by these drinks. Oxidation of X yields an organix acid Y, which is
present in vinegar. Name the compounds X and Y.

Answer 1

Answer:

a) X is ethene [CH2 = CH2]. It will neither dissolve in water nor conduct electricity because it is a covalent compound. It has a low melting point.

b) Here 'X' is ethanol (C2H5OH) which is an essential constituent of urine and beer and T is acetic acid (CH3COOH), which is present in vinegar.
