Differentiate:
(a). 1-Hexanol and 1-chlorohexane
(b). Diethyl ether and n-butanol
(c). Diethyl ether and n-pentane

Explanation

(a) 1-hexanol reduces organ red `CrO_(3)` to green `Cr^(3+)`, while 1-chlorohexane gives white ppt. of AgCl on warming with ethanolic `AgNO_(3)`
(b). `n`-butanol gives a positive test with `CrO_(3)` n acid and evolves `H_(2)` with sodium while dry ethyl ether is negative to both test.
(c). Unlike `n`-pentane, diethyl ether is basic and dissolves in conc. `H_(2)SO_(4)`
`(C_(2)H_(5))_(2)O+H_(2)SO_(4)to(C_(2)H_(5))_(2)OH^(+)+HSO_(4)^(-)`
