Functional groups who are they?

What are the main functional groups?

• the C - O - C group in the ethers;
• the -CO-O- group in esters;
• the -CO-NH- group in the amides.

What does functional group mean?

A functional group is an atom or group of atoms that determines the chemical properties of an organic compound, allowing its classification.

What are the summarized functional groups?

Functional groups are specific combinations of atoms that give molecules characteristic properties. There are several types of functional groups, each typical of a given compound. ... Alcohols are organic compounds similar to alkanes, in which an oxygen atom is replaced by a hydroxyl -OH group.

How to find the name of an organic compound?

the name consists of the list of branches preceded by the number of each atom of the main chain that hosts them, followed by the name of the main chain. The name should be written as a single word and remember that the prefixes di-, tri- etc. they do not contribute to the alphabetical order of the substituents.

Functional groups

Where is there an aldehyde group?

In nature they are produced in the fermentation processes of sugars. The divalent functional group C = O. it is called carbonyl (or "carbonyl group") and is common to aldehydes (R-CHO) and R-CO-R 'ketones, where R or R' are alkyl or aryl groups.

What are the functional groups of alcohols?

The functional group of an alcohol is the –OH (hydroxyl) group bonded to an sp3 hybridized carbon atom. The oxygen atom of alcohol is also sp3 hybridized.

What is meant by group R?

R in organic chemistry, is the symbol of the hydrocarbon chain. R is often used in formulas to indicate a generic alkyl group.

What are Alkyl groups?

In organic chemistry, alkyl (or alkyl group) is the generic name of the functional group corresponding to an alkane deprived of a hydrogen atom.

Which functional group contains nitrogen?

The amino group is a functional group and is present in amines. They contain nitrogen and can be considered as deriving from ammonia by replacing one, two or three hydrogen atoms with as many alkyl or aryl groups. ...

What is the functional group of alkenes?

1 ALKENES The alkenic functional group consists of two sp2 hybridized C atoms linked by a p and s bond. The 2 Cs of C = C and the 4 atoms directly bonded to C = C are all arranged on the same plane.

What is the functional group of halides?

Alkyl halides have the general formula R - X, where R is an alkyl group and X, the functional group, is a halogen. They can be divided into primary, secondary or tertiary depending on whether the halogen carbon is bonded to one, two or three alkyl groups.

What are the functional groups that characterize carbohydrates?

From the chemical point of view, carbohydrates correspond to polyhydroxyaldehydes or polyhydroxyketones or to compounds capable of producing these molecules by hydrolysis. This definition immediately identifies the functional groups present: aldehyde group (CHO), ketone group (C = O) and alcoholic OH functions.

What are the Halogen derivatives?

sm. [halogen + derivative]. Organic derivative obtained by replacing one or more hydrogen atoms of the molecule of an organic compound with as many atoms of a halogen; therefore there may be some fluoro derivatives, bromide derivatives and iodine derivatives.

When is Benzene a Substituent?

Phenyl, as mentioned, is a residue that derives from benzene by eliminating a hydrogen atom. It must be understood as a substituent of another molecule. ... if an ethyl group (-CH6-CH5) is bound on the free bond of phenyl C2H3- then we have ethylbenzene C6H5-CH2-CH3.

What is R in organic chemistry?

In particular, in organic chemistry, ar. it is the hydrocarbon part, aliphatic or aromatic, of an organic molecule that remains unaltered in non-destructive and non-destructive reactions (eg, in substitution reactions). You can have r. monovalent (r.

What is r in chemistry?

radio (or radium) Chemical element, radioactive, symbol Ra, atomic number 88, atomic weight 226,025. ... 226, radon, and various isotopes of other elements. There are 4 natural isotopes of r., R.

When is a carbon chiral?

The central atom has sp3 hybridization and is linked to four different substituents, it is called chiral carbon. There is another molecule in which the same atoms are mirrored to the central atom. enantiomers. to the mirror image of the molecule a.

Which alcohols are water soluble?

Methyl, ethyl, n-propyl, isopropyl, t-butyl and many polyhydric alcohols are completely miscible in water. The others vary from being weakly soluble to insoluble, according to the number of carbon atoms they have for each oxydirlic group.

How to recognize alcohols?

Alcohols are organic compounds with a structure similar to alkanes, in which a hydrogen atom is replaced by a hydroxyl group (-OH), therefore having the basic formula CnH (2n + 1) OH.

Which functional group characterizes ketones?

Ketones, or acetones, are organic compounds with the general formula R-CO-R ', characterized by the presence of a carbonyl group C = O. whose carbon, with sp2 hybridization, is directly linked to two hydrocarbon R groups which can be both aliphatic and aromatic.

How are aldehydes obtained?

Aldehydes can be obtained by oxidation of primary alcohols. Ketones, on the other hand, can be obtained by oxidation of secondary alcohols. In this regard, see: oxidation of alcohols.

What is the functional group of aldehydes and what differentiates it from that of ketones?

Aldehydes and ketones are compounds both containing the carbonyl group C = O. The functional group of an aldehyde is a carbonyl group bonded to at least one hydrogen atom. The functional group of a ketone is a carbonyl group bonded to two carbon atoms.

Who is more acidic between aldehydes and ketones?

The α-hydrogens of the ketones have lower acidity than those of the aldehydes since the two R groups linked to the carbonyl carbon present in the ketone send charge density to the carbon in α due to an inductive effect which is therefore less suitable for forming the carbanion.
