Is nitrophenol poisonous?
4-nitrophenol appears as a white to light yellow crystalline solid. Contact may severely irritate skin and eyes. Poisonous by ingestion and moderately toxic by skin contact.
When para nitro phenol toxicity causes a disease called as?
Toxicity. 4-Nitrophenol irritates the eyes, skin, and respiratory tract. It may also cause inflammation of those parts. It has a delayed interaction with blood and forms methaemoglobin which is responsible for methemoglobinemia, potentially causing cyanosis, confusion, and unconsciousness.
Is nitrophenol more acidic than phenol?
The nitro-group is an electron-withdrawing group. The presence of this group in the ortho or para position decreases the electron density in the OH bond. As a result, it is easier to lose a proton. Hence, ortho and para nitrophenols are stronger acids than phenol.
What is the hazardous obtained by 4 nitrophenyl Carciogene?
* Exposure to 4-Nitrophenol can cause upset stomach, weakness, confusion, rapid heartbeat and/or fever. * High or repeated exposure may affect the nervous system. * 4-Nitrophenol is a REACTIVE CHEMICAL and an EXPLOSION HAZARD.
What is nitrophenol used for?
4-Nitrophenol is used to manufacture drugs, fungicides, insecticides, and dyes and to darken leather. Acute (short-term) inhalation or ingestion of 4-nitrophenol in humans causes headaches, drowsiness, nausea, and cyanosis (blue color in lips, ears, and fingernails).
How will you separate o-nitrophenol or p-nitrophenol?
A mixture of o-nitrophenol and p-nitrophenol can be separated by steam distillation.
Why is o-nitrophenol more acidic than m-nitrophenol?
NO2 group at o and p position withdraws electron of o-h bond towards it by stronger M-effect while the NO2 group at m position withdraws electron of o-h bond by weaker I -effect . Thus o and p are nitrophenols are more acidic than m-nitrophenol.
Why p-nitrophenol is more soluble than o-nitrophenol?
Due to intramolecular H-bonding, −OH group is not available to form a hydrogen bond with water. Hence o-nitrophenol is sparingly soluble in water while m- and p-nitrophenol are soluble due to intermolecular H-bonding with water.
What is the functional group of 4-nitrophenol?
4-Nitrophenol (also called p-nitrophenol or 4-hydroxynitrobenzene) is a phenolic compound that has a nitro group at the opposite position of the hydroxyl group on the benzene ring.
Is 4-nitrophenol soluble in water?
4-Nitrophenol is a colorless to light yellow solid with very little odor. 2-Nitrophenol is slightly soluble in cold water, but 4-nitrophenol is moderately soluble in cold water.
