Question

chemical test to distinguish between propan-1-ol from propan-2-ol

Answer 1

Lucas Reagent test.

Propan-1-ol is a primary alcohol, it will show turbidity on mixing with Lucas Reagent (mixture of hydrochloric acid and zinc chlorate) only on moderate heating.

Propan-2-ol is a seccondary alcohol, it will show turbidity after 5-10 min. with reagent without heating.

 

CH3-CH(OH)CH3 +PCl5 --------->CH3CH(Cl)CH3 + POCl3+HCl

 Chlorobenzene and Benzyl chloride



Chlorobenzene will not give white precipitate.

Benzene is an electron rich molecule. Nucleophiles on the other hand seek electron deficient sites. This is why; benzene do not undergoes nucleophiles substitution reactions very easily.
