The correct statement regarding a SN2 reaction is/are
  • a)
    reaction involving stronger bond formation to α-carbon occur at faster rate
  • b)
    reaction shows kinetic isotopic effect
  • c)
    substitution of   lower the activation energy of reaction
  • d)
    presence of electron withdrawing group in substrate increases reactivity
Correct answer is option 'B,C,D'. Can you explain this answer?
Verified Answer
The correct statement regarding a SN2 reaction is/area)reaction involv...
Stronger bond formation at α-carbon affects the stability of product (thermodynamics) not the rate (kinetics) of reaction. Change of isotope at α-position or in halogens affect the rate, hence show kinetic isotopic effect. Presence of electron withdrawing group in substrate increases electrophilicity of α-carbon hence, increases its reactivity towards nucleophiles.
