Alcohols contain a hydroxyl group bonded to a carbon atom from "summary" of Organic Chemistry by John E. McMurry
Alcohols are organic compounds that are characterized by the presence of a hydroxyl group (-OH) bonded to a carbon atom. This distinctive functional group gives alcohols their unique properties and reactivity. The hydroxyl group consists of an oxygen atom bonded to a hydrogen atom, which is attached to a carbon atom in the alcohol molecule. The general formula for alcohols is R-OH, where R represents an alkyl group. Alkyl groups are simply chains of carbon and hydrogen atoms that are attached to the hydroxyl group. The alkyl group can be a simple straight chain, branched chain, or even a cyclic structure. The nature and size of the alkyl group attached to the hydroxyl group can greatly influence the physical and chemical properties of the alcohol. Alcohols can be classified into different types based on the number of carbon atoms bonded to the carbon atom carrying the hydroxyl group. Primary alcohols have one alkyl group bonded to the carbon atom, secondary alcohols have two alkyl groups, and tertiary alcohols have three alkyl groups. This classification is important because it affects the reactivity and stability of the alcohol molecule. The hydroxyl group in alcohols is polar due to the electronegativity difference between oxygen and hydrogen. This polarity gives alcohols the ability to form hydrogen bonds with other molecules, making them versatile solvents in various chemical reactions. The presence of the hydroxyl group also imparts acidity to alcohols, allowing them to act as weak acids in certain reactions.- The presence of a hydroxyl group bonded to a carbon atom is a defining feature of alcohols. This functional group gives alcohols their characteristic properties and plays a crucial role in their behavior in chemical reactions. Understanding the structure and reactivity of alcohols is essential in organic chemistry, as they are widely used in various industries and research fields.
