Question

Compound ' $A^{\prime }$ (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 ' $C$ '

Answer 1

Answer: 21

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.
