What is functional group?

Answer 1

On the Formulas tab you have the Function Library group, which consists of the various categories of functions that Excel provides. You can click on one of these to open a category and find a function that you want to use.

Answer 2

The chemically reactive groups of atoms within an organic molecule. They are the parts involved in chemical reactions and give organic molecules distinctive chemical properties. Some basic functional groups are Hydroxyl, carbonyl, carboxyl, amino, phosphate, methyl.

Answer 3

In organic chemistry, functional groups are lexicon-specific groups of atoms or bonds within molecules that are responsible for the characteristic chemical reactions of those molecules. The same functional group will undergo the same or similar chemical reaction(s) regardless of the size of the molecule it is a part of. However, its relative reactivity can be modified by nearby functional groups.

The word moiety is often used synonymously with "functional group," but, according to the IUPAC definition,[3] a moiety is a part of a molecule that may include either whole functional groups or parts of functional groups as substructures. For example, an ester (RCOOR') has an ester functional group (COOR) and is composed of an alkoxy moiety (-OR') and an acyl moiety (RCO-), or, equivalently, it may be divided into carboxylate (RCOO-) and alkyl (-R') moieties. Each moiety may contain additional functional groups--for example, methyl para-hydroxybenzoate contains a phenol functional group within the acyl moiety.

Combining the names of functional groups with the names of the parent alkanes generates a powerful systematic nomenclature for naming organic compounds.

The atoms of functional groups are linked to each other and to the rest of the molecule by covalent bonds. When the group of covalently bound atoms bears a net charge, the group is referred to more properly as a polyatomic ion or a complex ion. Any subgroup of atoms of a compound also may be called a radical, and if a covalent bond is broken homolytically, the resulting fragment radicals are referred as free radicals.

The first carbon atom after the carbon that attaches to the functional group is called the alpha carbon; the second, beta carbon, the third, gamma carbon, etc. If there is another functional group at a carbon, it may be named with the Greek letter, e.g., the gamma-amine in gamma-aminobutanoic acid is on the third carbon of the carbon chain attached to the carboxylic acid group.

Answer 4

grouping of atoms that occur again and again, even in very different types of molecules

Answer 5

Reoccurring clusters of atoms that greatly influence the chemical properties of molecules they are part of.

Answer 6

functioal groups are Alcohols , Aldehydes etc........ by abele,mera,abass. thomas

Answer 7

A group of atoms responsible for the characteristic behavior of the class of compounds in which the group occurs, as the hydroxyl group in alcohols.

Answer 8

The functional group of organic compounds is responsible for the reactions of this molecule.

Answer 9

Aminos, Phosphates, and Carbonyls.
