Q22 / 62 · NTA Abhyas (JEE Main) 2020 · Chemistry · Haloalkanes and Haloarenes

The reaction condition leading to the best yield of C 2 H 5 Cl are

  • Correct answer
    A
    C 2 H 6 ( excess )+C l 2    → UV  light
  • B
    C 2 H 6 +C l 2 ( excess ) → room  temp. dark
  • C
    C 2 H 6 +C l 2    → UV  light
  • D
    C 2 H 6 +C l 2 ( excess )   → UV  light

Solution

During chlorination of alkane, if excess of alkane is treated with   Cl 2 ( g )  in presence of light or heat, chance of mono–chlorination predominant.

  C 2 H 6 ( excess )+C l 2    → UV  light CH 3  C H 2  Cl +HCl

Hence, the correct answer is option: 'A'.
