MCQ
Compound A (molecular formula C5​H10​) gives only one monochlorinated product. Write the structure of compound A.
  • A
    1-pentene
  • B
    2-pentene
  • C
    1-methyl cyclobutane
  • D
    Cyclopentane

Answer

  1. Cyclopentane

Explanation:

Cyclopentane $\xrightarrow{\text{Cl}_2​+\text{hv}}$​ Cyclopentylchloride

Compound A has molecular formula C5​H10​.

The degree of unsaturation is 1. It should have either one double bond or should be a cyclic compound. If it has one double bond, then it will give many monochlorinated products.

However, it gives only one monochlorinated product. So, it is a cyclic compound. Thus, it should be cyclopentane.
