Aqueous alcohol solutions are not appropriate for surface decontamination because of the evaporative nature of the solution; a contact time of ten minutes or more is necessary and not achievable using a 70% (v/v) aqueous solution of ethanol. The resulting acetaldehyde is also toxic and is further oxidized to acetic acid and eventually The use of phenol as a neurolytic agent: a review.

The main reason for its stability is the delocalisation of electrons . The word "phenol" is used to describe a specific compound (hydroxybenzene) but is also used as the parent name when substituents are attached Boiling Point of Alcohol Comparison The boiling point of ethanol is much higher than the other two compounds in the first example in this image as a result of hydrogen-bonding interactions that occur . Which is more acidic, alcohol or phenol? Alcohols are very weak acids (somewhat weaker than water) but may loose H + from the OH group if sodium or a sufficiently strong base is present ; Phenol is more acidic than alcohols and H + may be removed with sodium hydroxide solution. Phenol is the simplest alcohol while benzoic acid is the simplest aromatic carboxylic acid. Aliphatic alcohol acts as a weak acid in presence of any strong base. Alcohols are chemical compounds in which a hydroxyl group replaces the hydrogen atom of an aliphatic carbon. Phenols are more acidic in comparison with alcohol and need to be diluted before use.

In phenol, it is attached to a benzene ring. Phenol is also used in making chemical compounds such as phenol red and phenylketone. Methods: Twenty patients with hemiplegic stroke were included. Phenols ,however, are stronger acids than water because they form phenoxide ion on losing a proton which is resonance stabilized. Explain why many alcohols are soluble in water. When antiseptic techniques were first introduced in the 1860s by Joseph Lister, it was phenol (or carbolic acid, as it was then known) that was used. Phenols : Phenols, like alcohols, are either colourless liquids or solids. It is a colourless, odourless, viscous and hygroscopic liquid. Phenol is more acidic than cyclohexanol and acyclic alcohols because the phenoxide ion is more stable than the alkoxide ion. Phenol: An alcohol where the hydroxyl group is bound to a phenyl group, with the formula C6H5OH. Phenols are much more acidic than alcohols because the negative charge in the phenoxide ion is not localized on the oxygen atom , as it is in an alkoxide ion, but is delocalized-it is shared by a . Phenols can also be named as carbolic acids. Alcohol. In phenol, it is attached to a benzene ring. of 2,4,6-tribromophenol (discussed in electrophilic substitution in phenol).

Another class of alcohols are the phenols, in which an OH group is attached to an aromatic ring, as shown in the figure below. Although phenols are more acidic compared to alcohols, we can say that phenols are considered as a subset of alcohol.
