Exploring Alcohols: Properties, Uses, and Reactions


– contain Hydroxyl group (OH) – suffix ol or hydroxy if a higher priority group is present- Diols contain two hydroxyl groups. * Geminal: 2 Hydroxyl groups on the same carbon* Vicinal: on adjacent carbons

1. What are alcohols?
Alcohols are a group of organic compounds that contain one or more hydroxyl (-OH) group attached to a carbon atom. They can be classified as primary, secondary, or tertiary alcohols depending on how many alkyl groups are attached to the carbon atom that bears the hydroxyl group.

2. What are the properties of alcohols?
Some common physical properties of alcohols include: they have a lower boiling point than corresponding carboxylic acids with similar molecular weights due to the fact that they cannot form intermolecular hydrogen bonds. Alcohols are generally soluble in water, and they exhibit weak acidic properties due to the presence of the hydroxyl group, which can donate a proton in aqueous solution.

3. What are the uses of alcohols?
Alcohols have several uses in both industry and daily life. Ethanol is used as a fuel additive, in the production of perfumes, and as a solvent. Methanol is used as a fuel and solvent, and in the production of formaldehyde and other chemicals. Isopropanol is used as an antiseptic and solvent. Ethylene glycol is used as an antifreeze and in the production of polyester compounds. Alcohols are also used in the manufacture of cosmetics, pharmaceuticals, and plastics.

4. What are some reactions of alcohols?
One of the most common reactions of alcohols is dehydration, which involves the loss of water from the hydroxyl group to produce an alkene. This reaction is typically catalyzed by a strong acid or base. In the presence of oxidizing agents such as potassium dichromate, primary alcohols can be oxidized to aldehydes or carboxylic acids, while secondary alcohols can be oxidized to ketones. Tertiary alcohols are generally resistant to oxidation. Alcohols can also undergo substitution reactions, in which the hydroxyl group is replaced by another functional group.

5. What are some examples of alcohols?
Some common examples of alcohols include methanol (CH3OH), ethanol (CH3CH2OH), and isopropanol (CH3CHOHCH3). These are all simple alcohols with one hydroxyl group. Other alcohols include ethylene glycol, which has two hydroxyl groups and is used as an antifreeze, and glycerol, which has three hydroxyl groups and is used in the production of soaps and other cosmetics.
