Phenol does not show intramolecular hydrogen bonding.
Q. What happens when many water molecules come into contact with one another?
What happens when 2 water molecules come in contact with each other, does the orientation of the water molecules matter? When they come into contact with each other they are attracted to each other and the orientation matters because the Hydrogen of one molecule will align with the Oxygen in another water molecule.

Q. What happens when 2 water molecules interact?
When the hydrogen atoms of 2 different water molecules come together, they repel. When an oxygen atom and a hydrogen atom from two different water molecules come together, they attract.
Q. Does intramolecular hydrogen bonding exist in 4 Nitrophenol?
The intermolecular hydrogen bonding is present in phenol m-nitrophenol and p-nitrophenol.
Q. Which type of hydrogen bonding is present in ortho nitro phenol?
Intramolecular H−bonding
Q. What does a phenol look like?
Phenols are similar to alcohols but form stronger hydrogen bonds. Thus, they are more soluble in water than are alcohols and have higher boiling points. Phenols occur either as colourless liquids or white solids at room temperature and may be highly toxic and caustic.
Q. What is the test for phenol?
Observations:
| Litmus test | Phenol turns blue litmus paper red. |
|---|---|
| Ferric chloride test | Violet or blue colouration shows presence of phenol. |
| Libermann’s test | Deep blue colour solution shows presence of phenol. |
| Bromine water test | Formation of white precipitate shows presence of phenol. |
Q. Why are phenols not considered as alcohol?
Phenols have unique properties and are not classified as alcohols. They have higher acidities due to the aromatic ring’s tight coupling with the oxygen and a relatively loose bond between the oxygen and hydrogen.
Q. What happens when phenol falls on skin?
The major hazard of phenol is its ability to penetrate the skin rapidly, causing severe burns. Toxic and even fatal amounts of phenol can be absorbed through relatively small areas of skin. Due to its local anesthetizing properties, skin burns may be painless.
Q. Is phenol harmful for skin?
Toxicity. Phenol and its vapors are corrosive to the eyes, the skin, and the respiratory tract. Its corrosive effect on skin and mucous membranes is due to a protein-degenerating effect. Repeated or prolonged skin contact with phenol may cause dermatitis, or even second and third-degree burns.
Q. Why does phenol burn skin?
Concentrated phenol may cause second- or third-degree burns because of its caustic and defatting (hydrophobic effect of phenol) properties [4,5]. However, prolonged skin contact with phenol will cause deep burns and elicit denaturation and gangrene followed by necrosis [6].
Q. Can phenol cause blindness?
Eye: Splashes with phenol may cause severe damage and possibly blindness. Ingestion: May produce vomiting, nausea coma and death.
