A little KNO3 is taken in a clean and dry test tube,added one or two drops of con CH2SO4.Then heated what will you observe?

Draw the structure of a chiral molecule,which contains a halogen atom.Draw the three-dimensional structure of the two enantiomers of the compound and name each according to the Cahn-Ingold-Prelog rules

) Design a continuous distillation column to recover benzene from a mixture of A mole % benzene and the rest is toluene. The top product contains B mole % benzene and the bottom product contains C mole % benzene. The column is operated at atmospheric pressure and the feed enters in to the column as saturated liquid. The reflux ratio is 40% excess of minimum value. Select a suitable tray and column internals with appropriate.
