1-Phenol (carbolic acid) is acidic in nature and turns blue litmus red while alcohol (ethanol) does not, 2-phenol gives violet or blue colour with neutral ferric chloride solution while alcohol does not, 3-phenol freezes to a solid in fridge while alcohol does not, 4-phenol produces bubbles on rough iron surface while alcohol does not.

What are the major differences between alcohol and phenol?
Chemically, the major difference between phenol and alcohol is that phenol is a hydroxyl unit attached to a benzene ring and alcohol has a hydroxyl unit attached to a carbon chain. More generally the major difference is that swallowing a small amount of phenol can kill you. Swallowing a small amount of alcohol (ethanol) may give you a buzz, but you would have to drink a great deal for it to kill you quickly.
Which one give violet color with neutral ferric chloride Salicylaldehyde glycerol benzyl alcohol ethanol?
i think phenol............
Give a simple procedure to convert anisole into phenol?
in the presence of con.h2so4 anisole will convert into phenol and hi
Why does phenol give a violet colouration with neutral FeCl3?
It is a test for presence of phenol. Fe itself is a transition metal that form a complex ions with phenol. Hence, the Fe can undergo d-d transition that give a colour which is purple in this case.
Does phenol give a positive biuret test?
No. The Biuret test only gives a positive result if a peptide bond exists. Phenol doesn't have a peptide bond, so it will not give a positive test.
Why phenol do not give protonation reaction readly?
Electron density on oxygen in phenoxide ion is decreased due to resonance. The oxygen rather acquire a positive charge. Therefore phenol does not give protonation readily
How does combining elements into a compound affect their properties?
They will either bind on a mollecular scale to form "solutions", or on a non-mollecular scale to form "mechanical mixtures". Certain properties will cause the mixture to combust, give off gasses, or other things, depending on the elements and the ratios.
How to convert aniline to picric acid?
React aniline with HCl/NaNO2 (diazotisation) followed by reaction with KOH to give phenol. Nitration of phenol with fuming nitric acid gives picric acid (or trinitrophenol).
What is the chemical equation of the reaction between phenol and calcium hydroxide?
Calcium hydroxide, a base, will reaction with phenol, a weak acid in a neutralization reaction to give a salt (calcium phenoxide (Ca(PhO-)2) and water.
Why do ibuprofen and naproxen not give a positive test with 1 percent ironIII chloride?
Iron (III) Chloride reacts with the Phenol group. Ibuprofen and Naproxen do not have a phenol group. Acetaminophen, on the other hand, does have a phenol group with would indicate a positive test (purple color change) with in the presence of Iron (III) Chloride.
