What are alcohols and phenols?
Alcohols are organic molecules that contain a hydroxyl (-OH) group. Phenols are molecules that contain an –OH group that is directly attached to a benzene ring.
How are phenols and alcohols different?
Phenols have a hydroxyl group directly linked to the ring, whereas alcohols, as non-aromatic compounds, have a hydroxyl group linked to the main chain. The difference is one is cyclic, and the other is non-cyclic.
What is the functional group of alcohol and phenol?
The hydroxyl group (—OH) is found in the alcohol and phenol functional groups.
What is general formula of alcohol and phenol?
Some of the properties of alcohols depend on the number of carbon atoms attached to the specific carbon atom that is attached to the OH group. … A primary (1°) alcohol is one in which the carbon atom (in red) with the OH group is attached to one other carbon atom (in blue). Its general formula is RCH 2OH.
Are all phenols alcohols?
A phenol consists of an -OH bonded to an unsaturated sp2 carbon. Thus, it does not qualify as an alcohol.
What are examples of phenols?
- Bisphenol A.
- Picric acid.
- Salicylic acid.
Why are phenols acidic than alcohols?
Phenol is more acidic than cyclohexanol and acyclic alcohols because the phenoxide ion is more stable than the alkoxide ion. In an alkoxide ion, the negative charge is localized at the oxygen atom. … Phenoxide ion is therefore resonance stabilized.
What does a phenol look like?
Phenol (also called carbolic acid) is an aromatic organic compound with the molecular formula C6H5OH. It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (−C6H5) bonded to a hydroxy group (−OH). Mildly acidic, it requires careful handling because it can cause chemical burns.
How will you distinguish between phenol and benzyl alcohol?
(i) Phenol turns blue litmus red but benzyl alcohol does not. (ii) Phenol gives a white precipitate with bromine water but benzyl alcohol does not.
What are the functional group of alcohol?
Alcohols contain the hydroxy functional group (-OH), bonded to a carbon atom of an alkyl or substituted alkyl group. The functional group of an alcohol is the hydroxyl group, –OH. Unlike the alkyl halides, this group has two reactive covalent bonds, the C–O bond and the O–H bond.
What is phenol used in?
Phenol is used primarily in the production of phenolic resins and in the manufacture of nylon and other synthetic fibers. It is also used in slimicides (chemicals that kill bacteria and fungi in slimes), as a disinfectant and antiseptic, and in medicinal preparations such as mouthwash and sore throat lozenges.
What are the 7 functional groups?
Functional groups include: hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl.
How do you classify phenol?
Depending on the number of hydroxyl groups attached, phenols can be classified into three types.
- Monohydric phenols: They contain one -OH group.
- Dihydric phenols: They contain two -OH groups. They may be ortho-, meta- or para- derivative.
- Trihydric phenols: They contain three -OH groups.
What is general formula of alcohol?
The general formula for the alcohols is C nH 2n+1OH (where n is the number of carbon atoms in the molecule).
What are the different types of alcohols?
There are three main types of alcohol: isopropyl, methyl, and ethyl. All are toxic, and only ethyl, or grain, alcohol can be consumed by humans, but the others find use as sterilizing agents, or as fuels.
