in Cl the resonance occurs from 3p orbitals but in F resonance occurs from 2p orbitals due this reason F increase electron density in conjugate base more as compare to Cl .

Which is more acidic phenol or para-chloro phenol?
Phenol. Anisole doesn't have any acidic protons.
In what products are phenol found in?
Phenol is found in nature in some foods, in human and animal wastes and in decomposing organic material.
What happens when sodium reacts with phenol?
NO NAVER no doubet the phenol is acidic in nature but not that much acidi to react with NaHCO3 Phenols are weakly acidic in nature. They turn blue litmus red and react with alkali metals and alkalies to form their salts. Phenol is weaker acid than carboxylic acid, hence does not react with sodium carbonate and sodium bicarbonate. The acidic character of phenol is due to the presence of polar O-H group. Because of larger electro negativity of oxygen atom, the electron pair of O-H bond is withdrawn more towards O and H+ ion can be easily released in aqueous solution. Phenols are more acidic than alcohols due to the presence of resonance
What are identification tests of phenol?
You add a specific ionic compound in a solution to determine if phenol or any of its derivatives are present. Ferric chloride (FeCl3) for example, can be used for such tests. Basically, when you mix the solution with the compound, the ions will interact with the phenol molecules or groups, and as a result, the solution will briefly change color. If there is no colour change in the solution, this suggest there is no phenol or phenol-based molecules in your solution.
What is the pka of bromophenol blue?
Phenols are acidic substances (pH over 7).
Why normal ferric chloride is not used in detection of phenol?
Normal solution of ferric chloride is acidic in nature and phenol is also acidic so neutral ferric chloride is more useful.
How will Calcium chloride react with phenol red and baking soda?
CaCl2 will NOT react with phenol red (an weakly acidic pH-indicator) and baking soda HCO3- ions.
Why are phenols acidic in nature?
Phenol can act as an acid due to it's stability as phenoxide ion. By releasing H+ ion it will form stable C6H5O- ion. The groups having +I, -I , +M , -M efffects present on phenol will effect acidic nature of phenol. As +I or +M groups which are present at ortho and at para psitions will decrease the acidic character of phenol. If they are at meta position effect is less than at para or ortho positions.Similar to this -I or -M gorups are substituted on phenol they will increase the acidic nature. so, we can say that as the stability of phenoxide ion increases acidic nature of phenol also increases.Phenol can act as an acid due to it's stability as phenoxide ion.

Give four properties of phenol to show how it differ from alcohol?
1-Phenol (carbolic acid) is acidic in nature and turns blue litmus red while alcohol (ethanol) does not, 2-phenol gives violet or blue colour with neutral ferric chloride solution while alcohol does not, 3-phenol freezes to a solid in fridge while alcohol does not, 4-phenol produces bubbles on rough iron surface while alcohol does not.
Is water more acidic than phenol?
No. Phenol is far more acidic than water.
Is p-nitrophenol a third degree alcohol?
No, it is no alcohol, it is a substituted phenol and is acidic in nature, while alcohols are neutral,.
What are the products of a reaction between phenol and magnesium chloride?
Phenol is so weakly acidic that it cannot react with metals low in the electrochemical series. Also, phenol reacts only with Sodium metal and no other. Hence, it does not react with Magnesium at room temperature.
Why is phenol more soluble in aqueous NaOH than in water?
Phenol is acidic in nature. The phenolate anion is stable through resonance. Hence, an acid base reaction ensues between phenol and NaOH in water resulting in the formation of sodium phenolate, which is highly soluble in water compared to phenol.
Which is more acidic p-chloro phenol or p-fluoro phenol?
p-chloro phenol is more acidic thisi is because in p-fluoro phenol as fluorine and carbon have identical 2p orbitals, the overlapping is perfect Hence the +r effect and -I effect cancels thus making it less acidic
What happened to phenol with Iron III chloride reagent?
"Addition of aqueous iron III chloride to a phenol gives a colored solution. Depending on the structure of the phenol, the color can vary from green to purple.
What is the Prepration of phenyl benzoate from phenol?
reacting a benzoyl chloride with a phenol to get an phenyl benzoate(ester).
Phenol are acidic in nature but alcohol not yet?
Phenol is more acidic than alcohols since the negative charge that is acquired by removal of a hydrogen atom can be delocalised into the molecules ring structure. acyclic alcohols cannot "spread" this charge as well as conjugated systems and thus will less readily lose their hydrogen atom.
