Report Sheet
What will occur with each test performed?
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
