Question

Write the chemical test to distinguish between Propan-1-ol and Propan-2-ol.

Answer 1

1. Lucas reagent is used to distinguish between primary, secondary, and tertiary alcohols based on their reactivity. Primary alcohols react slowly or not at all, while secondary alcohols react quickly to form an immediate turbid solution due to the formation of the corresponding alkyl chlorides.
2. Propan-1-ol (1-propanol) is a primary alcohol that reacts slowly with Lucas reagent, forming a turbid solution or precipitating over time.
3. Propan-2-ol (2-propanol) is a secondary alcohol and reacts rapidly with Lucas reagent, forming an immediate turbid solution.
