Why o-nitrophenol is major product in nitration of phenol?

Nitration of phenol with dilute nitric acid give the mixture of ortho-nitrophenol and para-nitrophenol. But the major product is ortho-nitrophenol(30\%–40\%). Since it is an electrophilic aromatic substitution reaction. In which Nitric acid (HNO3) is an electrophile and benzene ring is an nucleophile.

When phenol reacts with dilute nitric acid at room temperature the major product obtained is?

o-nitron p-nitrophenol
When phenol is treated with dilute nitric acid at room temper ed with dilute nitric acid at room temperature a mixture of o-nitron p-nitrophenol is obtained and o-nitrophenol is major product.

How does the nitration of phenol with dilute nitric acid differ from nitration of phenol with concentrated nitric acid in the presence of sulphuric acid?

The reaction of phenol with nitric acid is a mono-nitration reaction i.e. Only one hydrogen atom gets replaced per molecule of phenol. The reaction of phenol with concentrated nitric acid in the presence of sulphuric acid, however, is a tri-nitration reaction. …

What happens when phenol reacts with nitric acid?

With dilute nitric acid: Phenol reacts with dilute nitric acid at room temperature to give a mixture of 2-nitrophenol and 4-nitrophenol. With concentrated nitric acid: With concentrated nitric acid, more nitro groups substitute around the ring to give 2,4,6-trinitrophenol (common name: picric acid).

When phenol is nitrated by conc hno3 and h2so4 the product is?

The reaction of conc.

Why ortho nitro toluene is major?

Ortho nitrotoluene is a major product while para nitrotoluene is a minor product . Reasons: In case of reactivity: Ortho product is more reactive comparing with para product because electron density is more enriched at ortho position compared to the para position.

What happens when phenol reacts with dilute nitric acid at low temperature?

Dilute HNO3: Phenol reacts with dilute nitric acid at low temperature to give a mixture of ortho- and para-nitrophenol. Conc. H2SO4: At room temperature (298 K), phenol reacts with concentrated sulphuric acid to form o-phenolsulphonic acid.

What is the action of nitrating mixture on phenol?

Complete step-by-step answer:When nitrating mixture reacts with Phenol, it produces the isomers of phenol i.e. p-nitrophenol and o-nitrophenol.

What is the product obtained when phenol is nitrated with fuming nitric acid?

Nitro group is a deactivating group present here and so it is meta directing. Therefore, we can conclude that picric acid and m-dinitrobenzene are the products formed when phenol and nitrobenzene are treated separately with a mixture of concentrated sulfuric acid and concentrated nitric acid.

When phenol is heated with conc nitric acid in presence of conc Sulphuric acid it yields?

Phenol reacts with dilute nitric acid to give a mixture of ortho and para nitrophenol whereas phenol reacts with concentrated nitric acid to give picric acid or $2,4,6 – $trinitrophenol.

What is the molecular formula of phenol?
