Read the passage given below and answer the following questions:

Nucleophilic substitution reactions are of two types; substitution nucleophilic bimolecular (SN2) and substitution nucleophilic unimolecular (SN1) depending on molecules taking part in determining the rate of reaction. Reactivity of alkyl halide towards SN1 and SN2 reactions depends on various factors such as steric hindrance, stability of intermediate or transition state and polarity of solvent. SN2 reaction mechanism is favoured mostly by primary alkyl halide or transition state and polarity of solvent, SN2 reaction mechanism is favoured mostly by primary alkyl halide then secondary and then tertiary. This order is reversed in case of SN1 reactions.

Q. Which of the following is the correct order of decreasing SN2 reactivity?
  • a)
    RCH2X > R2CHX > R3CX
  • b)
    R3CX > R2CHX >RCH2X
  • c)
    R2CHX >R3CX > RCH2X
  • d)
    RCH2X >R3CX >R2CHX
Correct answer is option 'A'. Can you explain this answer?

Larger the number of alkyl groups at alpha-carbon atom, more is the steric hindrance and hence lesser the reactivity towards SN2 mechanism.
