How will you distinguish ethyl alcohol ,isopropyl alcohol and t-buctyl alcohol
Answers
Answer:
Explanation:
on the basis of Phyisical properties-Most of the common alcohols are colour less liquids at room temperature. Methyl alcohol, ethyl alcohol, and isopropyl alcohol are free-flowing liquids with fruity odours. The higher alcohols—those containing 4 to 10 carbon atoms—are somewhat viscous, or oily, and they have heavier fruity odours
Chemical properties-Ethanol and isopropnaol is 100% miscible with water while higher alcohols are partial or less miscible with water.
The most common test used to distinguish in between the primary, secondary, and tertiary alcohols are the Lucas test.
The Lucas reagent is a combined solution of HCl and ZnCl₂.
The primary alcohol (propanol) and the tertiary alcohol (tert-butyl alcohol) react with Lucas reagent and form products which are unstable and more stable respectively.
When the primary alcohol reacts, it gives a least stable reaction and so no turbidity is observed and the solution remains colourless.
When the tertiary alcohol reacts, it gives the most stable reaction and the solution turns turbid or cloudy quickly along with the formation of 2 differentiated layers at room temperature.
