# What chemical test can differentiate secondary and tertiary alcohols?

I have to perform a chemical test to determine whether the solution is a secondary or a tertiary alcohol. How can I do this? Please explain the procedure and the apparatus.

Or you can try the very simple Lucas' test using zinc chloride and concentrated hydrochloric acid: $$\ce{ROH + HCl -> RCl + H2O}$$
Tertiary alkyl nitrites show an absorption band at $\lambda$ = 400 nm, secondary and primary alkyl nitrites only below.
