whta are phenols? what is action of conc. H2SO4 at two different temperature on phenol.
Answers
Answer:Phenol reacts with different concentrations of sulphuric acid at different temperatures to yield different products. When phenol is heated at 100∘C with concentrated sulphuric acid, 4−hydroxy benzene sulphonic acid is formed. Reaction taking place is: SO3H group is sulphonic acid group and OH group is hydroxyl group.
Explanation:
Answer:
Phenol is an aromatic organic compound with the molecular formula C₆H₅OH. It is a white crystalline solid that is volatile. The molecule consists of a phenyl group bonded to a hydroxy group. Mildly acidic, it requires careful handling because it can cause chemical burns.
