|
|
They differ in both physical and chemical properties
|
|
|
They have different molecular formula
|
|
|
There are two types of isomerism; structural and stereoisomerism
|
|
|
Geometrical and optical isomerism are two types of stereoisomerism
|
Detailed explanation-1: -The incorrect option regarding isomerism is “They have a different molecular formula". Explanation: The compounds having identical molecular formulas are referred to as isomers. These compounds do not possess the same chemical and physical properties.
Detailed explanation-2: -Isomers are different compounds that have the same molecular formula but the atoms are attached in different ways.
Detailed explanation-3: -Isomers are molecules that have the same molecular formula, but have a different arrangement of the atoms in space.
Detailed explanation-4: -Two isomeric compounds, composed of exactly the same elements in exactly the same ratio, may have very different properties because of the different ways that the atoms are connected within the compounds.
Detailed explanation-5: -structural isomers: two substances having the same molecular formula but different physical and chemical properties because the arrangement of their component atoms is different.
