Question

How many isomers are possible for C$_4$H$_8$Cl$_2$ (including chain and positional)?

• A. 6
• B. 7
• C. 8
• D. 9

Hint:

Consider both chain and positional isomerism when calculating the number of possible isomers.

Answer 1

The Correct Option is B

There are 7 possible structural isomers for C$_4$H$_8$Cl$_2$, including positional and chain isomers. These can be achieved by varying the position of the chlorine atoms on the carbon chain.
