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
(A) Phenol forms reddish brown colouration with iron (III) chloride
(b) t-butyl alcohol gives turbidity (t-butyl chloride) with Lucas reagent immediately
(c) 2 - propanol is oxidised to 2 - propanone by chromic acid
(d) Yellow precipitate will be formed
