JEE Mains · Chemistry · STD 12 - 6. Haloalkanes and Haloarenes

यौगिकों \(CH _{3} Cl , CH _{3} CH _{2} Cl ,\left( CH _{3}\right)_{2} CHCl\) और \(\left( CH _{3}\right)_{3} CCl\) का \(S _{ N } 2\) क्रिया में क्रिया करण का उचित स्तर क्रम होता है:

  1. A \(CH_3Cl > (CH_3)_2CHCl > CH_3CH_2Cl > ( CH_3)_3CCl\)
  2. B \(CH_3Cl > CH_3CH_2 Cl > (CH_3)_2CHCl > (CH_3)_3CCl\)
  3. C \(CH_3CH_2 Cl > CH_3Cl > (CH_3)_2CHCl > (CH_3)_3CCl\)
  4. D \((CH_3 )_2CHCl > CH_3CH_2Cl > CH_3Cl > (CH_3)_3CCl\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(CH_3Cl > CH_3CH_2 Cl > (CH_3)_2CHCl > (CH_3)_3CCl\)

Step-by-step Solution

Detailed explanation

Rate of \({S_{{N^2}}} \propto \frac{1}{\text { Steric crowding of }^{\prime} C^{\prime}}\) As steric hindrance (crowding) increases, the rate of \({S_{{N^2}}}\) reaction decreases. The order of reactivity towards \({S_{{N^2}}}\) reaction for alkyl halides is Primary halides…
