Question

What type of isomerism is shown by pentane and 2-Methyl butane?

Answer 1

Structural isomerism

Answer 2

Answer: Structural isomerism is shown by pentane and 2-Methyl butane

Explanation:

Structural isomers is type of isomerism in which two different compounds have same molecular formula but differ in position of bonding of atoms or atomic organisation. For example: ethanol and propane shows this type of isomerism.

The molecular formula of pentane and methyl butane  is$C_5H_{12}$ same but arrangement of atoms are different in both. In pentane  branching is absent and in 2-Methyl butane branching is present.

Hence, showing Structural isomerism.
