What is a functional group give examples of four different functional groups?
What is a functional group give examples of four different functional groups?
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.
What are the four functional groups of amino acids?
All amino acids have the same basic structure, which is shown in Figure 2.1. At the “center” of each amino acid is a carbon called the α carbon and attached to it are four groups – a hydrogen, an α- carboxyl group, an α-amine group, and an R-group, sometimes referred to as a side chain.
What is functional group in biology?
Functional groups are groups of atoms that occur within organic molecules and confer specific chemical properties to those molecules.
What are the first 5 alcohols?
The four most common alcohols, which are also the simplest, are methanol (CH3OH), ethanol(C2H5OH), propanol (C3H7OH) and butanol (C4H9OH).
What is the name of COOH COOH?
Carboxylic acids are organic acids characterized by a carboxyl (-COOH) functional group….
| IUPAC name | ethanoic acid |
|---|---|
| Common name | acetic acid |
| Simpler formula | C2H4O2 |
| Structural formula | CH 3COOH |
How do you name a functional group?
The suffix of the name reflects the type(s) of functional group(s) present on (or within) the parent chain. Other groups which are attached to the parent chain are called substituents….
| Functional group | Prefix | Suffix |
|---|---|---|
| ketones | none | -one |
| alchols | hydroxy- | -ol |
| amines | amino- | -amine |
| ethers | alkoxy- | -ether |
What is a functional group Class 10?
Functional groups are group of atoms or bonds that define the function of the hydrocarbon that they get attached to. Examples: Alcohol, Aldehyde, Ketone, Carboxylic acid, Halogens, Double & Triple covalent bonds.
What is functional group topper?
A Functional Group represents an atom/ group of atoms, bonded to carbon chain and it defines the chemical property of the organic compound. For example, −OH represents hydroxyl group that is functional group of an alcohol.
What is Tetravalency class 10th?
Carbon has a valency of four, so it is capable of bonding with four other atoms of carbon or atoms of some other monovalent element. This is known as tetravalency of carbon.
What is difference between diamond and graphite?
For example, Graphite and diamond are two different allotropes of carbon….Explain the difference in properties of diamond and graphite on the basis of their structures.
| DIAMOND | GRAPHITE |
|---|---|
| 1) It has a crystalline structure. | 1) It has a layered structure. |
| 2) It is made up of tetrahedral units. | 2) It has a planar geometry. |
What is Catenation in simple words?
In chemistry, catenation is the bonding of atoms of the same element into a series, called a chain. The words to catenate and catenation reflect the Latin root catena, “chain”.
What is Catenation very short answer?
Catenation Definition: Catenation is the binding of an element to itself through covalent bonds to form chain or ring molecules. Examples: Carbon is the most common element that exhibits catenation.
What is the difference between Catenation and Tetravalency?
The key difference between catenation and tetravalency is that catenation includes the binding of atoms of the same chemical element to form chain or ring structures whereas tetravalency refers to the ability to form four covalent bonds.
What is Catenation explain?
Catenation, chemical linkage into chains of atoms of the same element, occurring only among the atoms of an element that has a valence of at least two and that forms relatively strong bonds with itself.
How is Catenation helpful to us?
Catenation is the linkage of atoms of the same element into longer chains. It helps to form longer chains and structure, hence vast number of organic compounds are found in nature and these organic compounds are essential for the sustenance of life.
Does germanium show Catenation?
That is the reason that carbon having least diffused or overlapped p-orbital have the ability to form long p-p σ-bonds. Next is germanium, this is normally not known to catenate much but recently germanium along with silicon and arsenic etc are reported in making double and triple bonds between semi-metallic elements.
Why does Carbon Show Catenation but not lead?
Since carbon is small atom, thus the bond formed between two carbon atom is strong. Therefore, it shows maximum catenation. And as we down the group, size of the atom increases, so M-M bond strength decreases and tendency to show catenation decreases.
Which element does not show Catenation in Group 14?
The element which doesn’t show catenation in group 14 is lead(Pb).
Which show has maximum Catenation property?
Carbon shows catenation to a maximum extent because of its electronic configuration and tendency to form strong covalent bonds.
Why is Group 14 called the carbon family?
The carbon family is also called the carbon group, group 14, or group IV. At one time, this family was called the tetrels or tetragens because the elements belonged to group IV or as a reference to the four valence electrons of atoms of these elements. The family is also called the crystallogens.
What is the symbol for lead?
Pb
