What is the triiodomethane reaction of phenol?
The triiodomethane (iodoform) reaction of phenol involves the conversion of phenol to iodoform in the presence of iodine and sodium hydroxide. The reaction proceeds through oxidation of phenol to benzoic acid, followed by further oxidation and degradation to iodoform. This reaction is commonly used as a test for the presence of a methyl group attached to a phenolic compound.
Does carbon dioxide undergo oxidation during photosynthesis?
yes
Why does the oxidation reaction undergo reduction?
Chemical reactions that result in transference of electrons
What are the products and reactants in an browning apple?
Browning of the apples is caused by the oxidation of the enzyme phenol oxidase:phenol oxidase + oxygen---------------melanins
When oxidation occurs does a substance undergo a chemical reaction a physical change or both?
Oxidation is a chemical reaction; but a physical modification can also occur.
How will you synthesis of phenol in small scale'?
There are many known syntheses of phenol. However, a few simple ones are: 1) hydrolysis of chlorobenzene: - chlorobenzene + water --> phenol + hydrochloric acid 2) oxidation of toluene: - toluene + oxygen --> phenol + carbon dioxide + water 3) oxidation of benzene with nitrous oxide: - benzene + nitrous oxide --> phenol + nitrogen
What is the role of beta-mercaptoethanol in DNA extraction?
stabilization of phenol against oxidation
How does diazepam undergo phase 1 metabolism?
Cytochrome P450 allows phenytoin to undergo aromatic hydroxylation to turn into phenol.

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.
