Question

Which of the following isomer of pentane C₅H₁₂ will give three isomeric monochlorides on photochemical chlorination?

Options

• \[\begin{array}{cc}
  \phantom{...}\ce{CH3}\\
  |\\
  \ce{CH3 - C - CH3}\\
  |\\
  \phantom{...}\ce{CH3}\\
  \end{array}\]

• CH₃CH₂CH₂CH₂CH₃

• \[\begin{array}{cc}
  \ce{CH3 - CH - CH2 - CH3}\\
  |\phantom{.........}\\
  \ce{CH3}\phantom{......}\\
  \end{array}\]

• All of the above

Answer 1

CH₃CH₂CH₂CH₂CH₃

Explanation:

When alkanes larger than ethane are halogenated, isomeric products are formed.
