Question

A hydrocarbon C5​H10​ does not react with chlorine in dark but gives a single monochloro compound C5​H9​Cl in bright sunlight. Identify the hydrocarbon.

​

Answer 1

The molecular formula of hydrocarbon is C5H10. It satisfies the general formula CnH2n . It suggests that the hydrocarbon is either alkene or cyclloalkane. It does not react with chlorine in dark. Hence, it cannot be alkene. Hence, it is cycloalkane. It gives a single monochloro compound C5H9Cl in bright sunlight. Hence, the hydrocarbon.is cyclopentane.

Answer 2

Answer:

The  molecular  formula of hydrocarbon is C5H10 thatbelongs to a group with a common formula known as CnH2n.

Hence, it may be cycloalkane or alkene.

The hydrocarbon never react with chlorine in dark, it cannot be an alkene.

Hence it is a cycloalkane.

Also, hydrocarbon provides one monochloro compound named C5H9Cl when reacting with the chlorine compound in extremely bright sun
