JEE Mains · Chemistry · STD 11 - 8.4. Organic chemistry reaction mechanism
Consider the isomers of hydrocarbon with molecular formula \(C_5H_{10}\). These isomers do not decolourise \(KMnO_4\) solution. These isomers are subjected to chlorination with chlorine in presence of light to give monochloro compounds. The total number of monochloro compounds (structural isomers only) formed is _______.
- A 11
- B 12
- C 13
- D 14
Answer & Solution
Correct Answer
(D) 14
Step-by-step Solution
Detailed explanation
The hydrocarbon with molecular formula \(C_5H_{10}\) has a degree of unsaturation of \(1\). Since its isomers do not decolourise \(KMnO_4\) solution, they do not contain any carbon-carbon double bonds. Thus, they must be cycloalkanes. The possible structural isomers of cyclic…
