In a preparation of ethane, ethanol is added a drop at a time to a heated reagent Y. The impure ethane is washed b being bubbled through a solution Z and then collected. What are reagent Y and Z likely to be?
Acidified K2Cr2O7 dilute NaOH
Concentrated H2SO4 dilute H2SO4
Concentrated H2SO4 dilute NaOH
