Test - 1-Butanol   2-butanol    2methyl-2 propanol 2 isopropyl unknown

1. Water

2. Ph

3. Iodoform

4.Lucas

5. Chromic acid

6. Iron (III) chloride

1.a What happens to phenol with iorn(III) chloride reagent?

b. What happens to t-butyl alcohol with Lucas reagent?

c. What happens to 2-propanol with chromic acid?

d. What happens to 2-butanol with NaI-I2 reagent?

Explanation / Answer

1a. When phenol reacts with FeCl3 it froms a green or violet color due to formation of (Ph-O)3Fe.

b. When t-butyl alcohol reacts with Lucas reagent it forms turbid solution due to formation of t-butyl chloride.

c. When 2-propanol reacts with chromic acid it oxidizes to Propanone.

d. When 2-butanol reacts with NaI in presence of I2, 2-iodo propane is formed
