Question

what is isomers? answer with examples

Answer 1

An isomer of a molecule has the same number of atoms of each element, but has a different arrangement of the atoms. It has the same molecular formula as the other molecule, but with a different chemical structure.



example

Butane and isobutane have the same number of carbon (C) atoms and hydrogen (H) atoms, so their molecular formulas are the same. However, each one has a different structural formula, which shows how the atoms are arranged. So we can say that butane and isobutane are structural isomers.

Answer 2

$\huge{Isomers\::}$


Molecules having same molecular formula, but different molecular structure is known as $\textbf{Isomers.}$ And this phenomena is known as Isomerism.



$\textbf{Example :}$


CH3CH2OH and CH3OCH3 have same molecular formula but different structure.



$\textbf{Types\::}$

There are two types of Isomers :-

1) Structural Isomers.

2) Stereoisomers.
