Hello

Isomers are different compounds that have the same molecular formula but the atoms are attached in different ways.

Isomers of C4H9Cl are :

Hope it helps.

Hello,

In chemistry, isomers are ions or molecules with identical formulas but distinct structures. Isomers do not necessarily share similar properties.

C4H9CL is  Chlorobutane or 1-Chlorobutane

Its Isomers are

• 2-Chlorobutane
• 1-Chloro,2-Methylpropane
• 2-Chloro,2-Methlypropane

By change the positions of chlorine. And by changing the nature of chain(branched or straight)

Hope this was helpful.
