In organic chemistry, a functional group is a specific group of atoms or bonds within a compound that is responsible for the characteristic chemical reactions of that compound . The same functional group will behave in a similar fashion, by undergoing similar reactions, regardless of the compound of which it is a part.
What are functional groups important?
Functional groups are collections of atoms that attach the carbon skeleton of an organic molecule and confer specific properties. ... Functional groups in biological molecules play an important role in the formation of molecules like DNA, proteins, carbohydrates, and lipids .
What is a functional group and why are they important?
Functional groups are important in chemistry because they are the portion of a molecule that is capable of characteristic reactions . They, therefore, determine the properties and chemistry of many organic compounds. An organic compound is any compound that contains carbon and another element.
What is the functional group function?
Functional groups are chemical motifs, or patterns of atoms, that display consistent “function” (properties and reactivity) regardless of the exact molecule they are found in.
How do you define functional groups?
Functional group, any of numerous combinations of atoms that form parts of chemical molecules , that undergo characteristic reactions themselves, and that in many cases influence the reactivity of the remainder of each molecule.
Is alcohol a functional group?
Alcohol is a functional group that you probably are familiar with. In organic chemistry, the term alcohol refers to a compound containing the OH (hydroxy) group . Depending on the position of the OH group, alcohols can also be categorized as primary (1°), secondary (2°) or tertiary (3°).
In which functional group oxygen is absent?
The functional group that does not contain an oxygen atom is e. amine .
What is functional group called?
Chemical properties of an organic molecule is determined not by the whole molecule but by a specific region in it, called the functional group of the molecule. ... That is, the CHO group, called the aldehyde group , is the functional group in 3 and 4. Organic Compounds are classified based on the functional group present.
What is a functional group give examples?
An atom/group of atoms joined in a specific manner which is responsible for the characteristics chemical properties of the organic compounds is called a functional group. Examples are hydroxyl group (-OH) , aldehyde group(-CHO), Ketonic group (-CO-),Carboxlic acid group(-COOH) etc.
How do you identify functional groups?
- atoms connected by non-aromatic double or triple bond to any heteroatom.
- atoms in nonaromatic carbon–carbon double or triple bonds.
- acetal carbons, i.e. sp3 carbons connected to two or more oxygens, nitrogens or sulfurs; these O, N or S atoms must have only single bonds.
What are the six main functional groups?
Hydroxyl, sulfhydryl, carbonyl, carboxyl, amino and phosphate groups .
What does R mean in functional groups?
R group: An abbreviation for any group in which a carbon or hydrogen atom is attached to the rest of the molecule . ... R is an abbreviation for radical, when the term radical applied to a portion of a complete molecule (not necessarily a free radical), such as a methyl group.
What is the functional group for aldehydes?
Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O . The carbon atom of this group has two remaining bonds that may be occupied by hydrogen or alkyl or aryl substituents.
What is alcohol functional 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 a functional group Class 10?
Functional groups are defined as one or more atoms of distinctive chemical properties no matter what they are attached to . The atoms that are present in the functional groups are linked to each other and to the rest of the molecules by covalent bonds.
Which are the functional groups?
