Compound 'A' (molecular formula C 3 H 8 O ) is treated with acidified potassium dichromate to form a product 'B' (molecular formula C 3 H 6 O ) . 'B' does not forms a shining silver mirror on warming with ammoniacal silver nitrate. 'B' when heated with concentrated sulphuric acid form 'C' which do not give test for unsaturation. Identify the sum of number of carbon and hydrogen atoms in compound 'C'

Correct answer

21

Step-by-step solution

Compound 'A' (molecular formula C 3 H 8 O ) is isopropyl alcohol. Compound 'B' (molecular formula C 3 H 6 O ) is acetone. With concentrated sulphuric acid acetone form mesitylene.
