Why is O-nitrophenol less soluble than p-nitrophenol?

Ortho -nitrophenol is less soluble in water than p-and m-nitrophenols because. o-nitrophenol is more volatile stema than those of the and p-isomers. There is intramolecular H-bonding in o-nitrophenol and thus solubility in water is decreased.

Why is O-nitrophenol less soluble than M nitrophenol in water?

Ortho-nitrophenol is less soluble in water than p- and m-nitrophenols because. o-nitrophenol is more steam volatile than m- andp-isomers. o-nitrophenol shows intramolecular H-bonding.

Why o-nitrophenol has lower boiling point than M and P isomer?

P-nitrophenol has intermolecular hydrogen bonding. Intermolecular hydrogen bonding results in a molecular association. This increases boiling point. Hence, O-nitrophenol contains a lower boiling point than P-nitrophenol.

Which isomer of nitrophenol is water soluble and why?

-m-nitrophenol has hydroxyl group in the meta position of the benzene ring of nitrophenol. There is distance between the OH- group and the nitro group and cannot form any intermolecular hydrogen bond. So, it is soluble in water due to the presence of free hydroxyl and nitro groups.

Which of the following is the least soluble in water?

BeF2>MeF2>CaF2>SrF2 so SrF2 is least soluble.

Do M and p-nitrophenol exist as associated molecules?

m- and p- Nitrophenols exist as associated molecules.

Do o-nitrophenol and p-nitrophenol have hydrogen bonding in their molecules explain which of the two has higher boiling point?

p-Nitrophenol has intermolecular hydrogen bonding so it has more boiling point and less volatile than o-nitrophenol which has intramolecular hydrogen bonding.

Which of the following have higher melting point and why P nitro phenol and o nitro phenol?

p-nitrophenol has a higher molecular weight than o-nitrophenol.

Why is he least soluble in water?

-Helium is an inert gas and is monatomic in nature. Due to its inert nature, it is non-polar as it has complete electrons in its shell and has complete octet. So, it is not soluble in water.

Why do gases have the least solubility in water?

The solubility of gases in water depends on the interaction of the molecules of water and the molecules of gas. The solubility of gases in liquid decreases with increase in temperature. Hence , gases are more soluble in cold water than hot water.

Why is O-nitrophenol less soluble in water than P- and M-nitrophenols?

Ortho -nitrophenol is less soluble in water than p-and m-nitrophenols because. o-nitrophenol is more volatile stema than those of the and p-isomers. Solution : There is intramolecular H-bonding in o-nitrophenol and thus solubility in water is decreased.

Why is ortho nitrophenol less soluble in water than para and meta?

Ortho Nitrophenol is less soluble in water than para and meta nitrophenols because Ortho Nitrophenol is more volatile in steam than those of Meta and Para isomers Ortho Nitrophenol shows Intramolecular hydrogen bonding Ortho Nitrophenol shows Intermolecular hydrogen bonding

Does nitrophenol show intermolecular hydrogen bonding?

Ortho nitrophenol shows intramolecular hydrogen bonding which lowers its interaction with water molecules. Meta nitrophenol and Para nitrophenol show intermolecular hydrogen bonding and these molecules can easily form hydrogen bonding with water molecules to make them water soluble.

Why is there no phenolic proton in O-nitrophenol?

In o-nitrophenol the phenolic proton is intramolecularly bonded to NO2 oxygen and is not easily available to interact with the solvent molecule (H2O). In m-nitrophenol and p-nitrophenol the phenolic proton is available for H-bonding interaction with H2O.
