In organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions. The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition.

Functional groups are structural units within organic compounds that are defined by specific bonding arrangements between specific atoms. For example the structure of capsaicin, found in chili peppers, incorporates several functional groups, labeled in the figure below and explained throughout this section.

2010年10月6日 · Functional groups are specific groupings of atoms within molecules that have their own characteristic properties, regardless of the other atoms present in a molecule. Common examples of functional groups are alcohols, alkenes, alkynes, amines, carboxylic acids, aldehydes, ketones, esters, and ethers, among others.

Functional groups are groups of one or more atoms with distinctive chemical properties regardless of what is attached to them. The atoms of functional groups are bound by covalent bonds with one another and with the rest of the molecule.

Functional groups are small groups of atoms that exhibit a characteristic reactivity. A particular functional group will almost always display its distinctive chemical behavior when it is present in a compound. Because of their importance in understanding organic chemistry, functional groups have specific names that often carry over in the naming of individual compounds incorporating …

2021年12月16日 · Functional groups are the most reactive parts in organic compounds, and determine the major properties of compounds. The summary of common functional groups is included in Table 2.2. Knowing the functional groups well is …

Functional groups refer to specific atoms bonded in a certain arrangement that give a compound certain physical and chemical properties. Functional groups are often used to “functionalize” a compound, affording it different physical and chemical properties than it …

A distinctive set of physical and chemical properties is imparted to molecules that contain a functional group composed of three pairs of doubly bonded atoms (usually all carbon atoms) bonded together in the shape of a regular planar (flat) hexagon.

2023年5月30日 · In organic chemistry, functional groups are the substituent atoms or groups of atoms that are connected to certain molecules. The halo group, alcohol group, aldehyde group, ketone group, carboxylic acid group, alkene group, alkyne group, etc. are some of the most important functional groups in organic chemistry.

2023年7月27日 · In organic chemistry, functional groups are one of the most reactive parts of organic compounds and determine the major characteristic of compounds. An organic complex has a backbone (skeleton) of carbon-carbon single bonds with different groupings of atoms, known as functional groups, connected at various locations.
