Butyl chloride gives possible isomers ?
Correct answer: C. 4
- A. 2
- B. 3
- C. 4
- D. 5
Explanation
The formula C4H9Cl has four structural isomers: 1-chlorobutane, 2-chlorobutane, 1-chloro-2-methylpropane and 2-chloro-2-methylpropane. These differ in the carbon skeleton or in the position of chlorine. The likely mistake is choosing 3 by counting only the straight-chain positional isomers and overlooking the two branched isomers.

About Isomerism
Isomerism occurs when compounds have the same molecular formula but different atom arrangements or spatial orientations. The content includes chain, position, functional, metameric and tautomeric isomerism, along with geometrical and optical isomerism, including cis-trans forms, E/Z notation, chirality and enantiomers.
