There are three types of structural isomers: chain isomers, functional group isomers and positional isomers. Chain isomers have the same molecular formula but different arrangements or branches. Also asked, what are the 3 isomers of pentane?
Skeletal isomerism
For example, there are three skeletal isomers of pentane: n-pentane (often called simply "pentane"), isopentane (2-methylbutane) and neopentane (dimethylpropane).
Subsequently, question is, what are isomers and its types? Isomerism is the phenomenon in which more than one compounds have the same chemical formula but different chemical structures. Chemical compounds that have identical chemical formulae but differ in properties and the arrangement of atoms in the molecule are called isomers.
Then, how many types of isomers are there?
two
Which are isomers?
Isomers are molecules that have the same molecular formula, but have a different arrangement of the atoms in space. That excludes any different arrangements which are simply due to the molecule rotating as a whole, or rotating about particular bonds. For example, both of the following are the same molecule.

Which are Metamers?
The metamerism arises when different alkyl groups are attached to same functional group. Diethyl ether, 2-methoxypropane, and 1-methoxypropane have the same functional group and molecular formula but different alkyl group present in the functional group. Therefore, they are metamers. How do you identify isomers?
You can tell them apart by their bonding patterns and how they take up three-dimensional space. Identify structural (constitutional) isomers by their bonding patterns. The atoms of the compounds are the same but they are connected in such a way as to make different functional groups. How are isomers named?
Optical isomers are so named due to their effect on plane-polarised light, about which you can read more here, and come in pairs. They usually (although not always) contain a chiral centre – this is a carbon atom, with four different atoms (or groups of atoms) attached to it. What does Stereoisomer mean?
Generally defined, stereoisomers are isomers that have the same composition (that is, the same parts) but that differ in the orientation of those parts in space. There are two kinds of stereoisomers: enantiomers and diastereomers. What are diastereomers give example?
Diastereomers may often include compounds which are ring structures. Imagine, for example, two compounds with a six-membered ring, each with two substituents, a chlorine atom and an ethyl group. They are also not mirror images of each other, just like our previous example, which defines them as diastereomers. Are diastereomers Superimposable?
Diastereomers are stereoisomers that are not mirror images of one another and are non-superimposable on one another. Stereoisomers with two or more stereocenters can be diastereomers. What is Catenation class 10th?
Catenation can be defined as the self-linking of atoms of an element to form chains and rings. What is a functional group Class 10?
An atom or a group of atoms present in the molecules, which determines the characteristics property of the organic compounds, is called the functional group. Organic compound. Functional group. What is space isomerism?
In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space. What is homologous series Class 10?
Homologous Series. Homologous Series. A series of carbon compounds in which same functional group substitutes the hydrogen atom is called a homologous series. These compounds have similar chemical properties due to the addition of same kind of functional group throughout the chain. What does enantiomer mean?
Enantiomers are chiral molecules that are mirror images of one another. Furthermore, the molecules are non-superimposable on one another. This means that the molecules cannot be placed on top of one another and give the same molecule. Chiral molecules with one or more stereocenters can be enantiomers. Why can't we have isomers of first three members of alkane series?
The First 3 membered, of the alkane series can't have isomers, because they will have the same structural formula. What are optical isomers?
Optical isomers are two compounds which contain the same number and kinds of atoms, and bonds (i.e., the connectivity between atoms is the same), and different spatial arrangements of the atoms, but which have non-superimposable mirror images. Each non-superimposable mirror image structure is called an enantiomer. Which is a pair of functional group isomers?
There are three functional group isomers of which you need to be aware: alcohols and ethers. aldehydes and ketones. carboxylic acids and esters.
