What is the substance for sodium phenoxide?
Sodium phenoxide is the sodium salt of phenol. It is formed when sodium hydroxide (NaOH) reacts with phenol (C6H5OH) in a neutralization reaction. Sodium phenoxide is commonly used in organic synthesis as a strong base.
Is sodium phenoxide soluble?
Yes, sodium phenoxide is soluble in water. It forms a clear, colorless solution due to the ionization of the sodium phenoxide molecule in water.
What happens when sodium phenoxide is reacted with CO2 and HCl?
When sodium phenoxide is reacted with CO2 and HCl, the phenoxide anion is protonated by HCl to form phenol. The phenol then reacts with CO2 to form salicylic acid.
What is the word equation for sodium phenoxide and carbon dioxide?
Sodium phenoxide reacts with carbon dioxide to form sodium salicylate and water.
Which one is more soluble in water phenol or sodium phenoxide ion?
Sodium phenoxide ion is more soluble in water than phenol. This is because sodium phenoxide ion is an ionic compound, which dissociates into ions in water and forms interactions with water molecules, increasing its solubility compared to the non-ionic phenol molecule.
What happens in the reaction of sodium phenoxide with sulforic acid?
In this reaction, the sodium phenoxide reacts with sulfuric acid to form phenol and sodium sulfate. The hydrogen from the sulfuric acid replaces the sodium in the phenoxide group, resulting in the formation of phenol. Sodium sulfate is formed as a byproduct.
What is phenoxide?
Phenoxide is the conjugate base of phenol, a type of benzene ring with an -OH group attached. It is an aromatic compound that can exhibit resonance stabilization due to delocalization of electrons within the benzene ring. Phenoxide is commonly seen in organic chemistry reactions as both a nucleophile and a base.
Why phenoxide ion is more reactive than phenol toward electrophilic subsititution reaction?
The phenoxide ion is more reactive than phenol towards electrophilic substitution reactions because the phenoxide ion is a stronger nucleophile due to the negative charge on oxygen. This makes it more effective in attacking electrophiles in substitution reactions. Additionally, the negative charge on the phenoxide ion stabilizes the transition state, lowering the activation energy for the reaction to occur.
What is the formula of sodium phenoxide and hydrochloric acid?
The formula of sodium phenoxide is NaC6H5O, and the formula of hydrochloric acid is HCl. When sodium phenoxide reacts with hydrochloric acid, it forms phenol (C6H5OH) and sodium chloride (NaCl).
How prepare the phenoxide?
To prepare the phenoxide, dissolve 23.5 grams of Csl-IsOl-I in 875 milliliters of toluene. On a separate dish, dissolve 10 grams of NaOH in 150 milliliters of methyl alcohol. Pour the solution into a flask and mix.
What happens when phenol is warmed with CCl4 in aqueous NaOH?
In the presence of aqueous NaOH, phenol undergoes nucleophilic aromatic substitution reaction to form sodium phenoxide. When CCl4 is added, no reaction occurs as CCl4 is non-reactive towards phenoxide ion.
Why phenols are more acidic than alcohols but less than carboxylic acids?
Phenols are more acidic than alcohols due to the resonance stabilization of the phenoxide ion formed upon deprotonation. This stability lowers the energy of the phenoxide ion, making it easier for phenols to donate a proton. However, carboxylic acids are more acidic than phenols because the carboxylate ion is stabilized by two electronegative oxygen atoms and resonance delocalization, resulting in further stabilization compared to the phenoxide ion.
