What are X and Y in the following reaction? CF ₂ Cl ₂ UV X+Y

Options

  1. A^ CF ₂ Cl , ^ Cl
  2. B⁻ C ₂ ~F ₄, Cl ₂
  3. C^ CFCl ₂, ^ F
  4. DCCl ₂, ~F ₂

Correct answer

A. ^ CF ₂ Cl , ^ Cl

Step-by-step solution

Since, chlorofluorocarbon compounds, i.e., freons (CFCs) are non-reactive, non-inflamable, non-toxic organic molecules, these are widely used in air conditioners, refrigerators, in electronic industry for cleaning computer parts. Due to very long life time ( CF ₂ Cl ₂-12: 139 . years, CFCl ₃-11 : 77 years), these compounds ultimately react the stratosphere where they get broken down by powerful UV radiations and release chlorine free radical. The chlorine free radicals react with ozone and cause its depletion. alig
