Which of the following statements is true about SN2
reactions?
A. SN2 reactions require a bulky base.
B. SN2 reactions require a substrate capable of forming a
carbocation. Strength of the nucleophile does not matter.
C. SN2 reactions require a strong nucleophile and an unhindered
substrate that is susceptible to back side attack.
D. SN2 reaction rates are not affected by concentration of the
substrate.
Which of the following statements is true about the affect
of leaving groups on SN1 and SN2 reactions?
Leaving group ability affects the rate of both SN1 and SN2
reactions.
Leaving group ability affects the rate of
SN2 reactions;, but leaving group ability does not
affect the rate of SN1 reactions.
Leaving group ability does not affect the rate of SN1 or
SN2 reactions.
Leaving group ability affects the rate of SN1 reactions,
but leaving group ability does not affect the rate of SN2
reactions.
