Why phenol have higher boiling point than cyclohexanol?
, Chemical Engineer. Because phenol has strong intremolecular force between its structure as it cintains 6 carban bonds, whereas alcohol contains 2 carbon bond relatively weaker than phenol, thats why phenol has high boiling point. Strictly speak, Phenol is an alcohol as it contains an OH group.
Why are phenols reactive?
Phenols are highly reactive toward electrophilic aromatic substitution, because the nonbonding electrons on oxygen stabilize the intermediate cation.
How can phenol be distinguished from Cyclohexanol?
Phenol gives violet colour with neutral FeCl3 solution while Cyclohexanol does not.
Why phenol have higher boiling point than alcohol?
Phenols generally have higher boiling points in comparison to other hydrocarbons with equal molecular masses. The main reason behind this is the presence of intermolecular hydrogen bonding between hydroxyl groups of phenol molecules.
Why is phenol more reactive than aniline?
In contrast, phenols and anilines (whose reactivity is enhanced by lone pairs on the oxygen or the nitrogen) are many more times reactive towards electrophiles. The lone pairs on phenol donate electron density to the entire ring, and the phenyl ring becomes MORE nucleophilic.
Why is phenol less reactive than benzene?
Phenol (which is a benzene ring with one substituted carbon with a hydroxyl or alcohol group) does not require a halogen carrier to be halogenated whereas benzene itself cannot react with a halogen alone.
Why ortho nitro phenol is more acidic than ortho methoxy phenol?
The nitro-group is an electron-withdrawing group. On the other hand, methoxy group is an electron-releasing group. Thus, it increases the electron density in the O-H bond and hence, the proton cannot be given out easily. For this reason, ortho-nitrophenol is more acidic than ortho-methoxyphenol.
Why is phenol a stronger acid than ethanol?
Phenol has a pKa value of around 10.00 while ethanol has a pKa value of around 16. So yes phenol is a stronger acid than ethanol. Lower pKa value means stronger acid. In phenol the OH group is bonded to a benzene ring while in ethanol it is bonded to an alkyl group.
Which phenol is the most acidic?
The most acidic phenol is 2-methyl-6nitrophenol [Answer (2)] The increasing order of the acidic nature is In 2-methyl-6nitrophenol it has one electro relea…
What is the reason for the acidic nature of phenol?
Explaining acidity of phenol. The acidity of phenol is because of its ability to lose the hydrogen ion forming phenoxide ions.
What are the effects of phenol?
Consuming phenol in its pure form can damage your esophagus, stomach, intestines, and other digestive organs. It can be fatal if you have enough of it at one time. Don’t put it on your skin. Pure phenol can damage your skin if it makes direct contact. This can include burns and blisters. Don’t inhale it.
