Question

An organic compound ’A' with molecular formula C2H60 gives compound 'B’ on oxidation with alkaline KMnO4. ’A’ an heating with conc. H2S04 gives ‘C' which on reaction with phosphoric acid and water gives back ‘A’. Compound ’C’ gives addition product with Br2 and H2. Identify A, B, C and write chemical equations involved.

Answer 1

1.compound A is ethanol.

C2H6O is isomer of ethanol.

2.Compound B is ethanonic acid. it forms due to oxidation.

3. compound C is ethene. sulphuric acid is a dehydrating agent. the product is CH2 double bond CH2 + water(H2O)
