Which of the following correctly ranks alkyl halides in order of their decreasing ease of undergoing an SN2 reaction based on steric factors?
Q1. Which of the following correctly ranks alkyl halides in order of their decreasing ease of undergoing an SN2 reaction based on steric factors?
Answer: Primary > Secondary > Tertiary
Explanation: Primary alkyl halides react fastest in SN2 due to minimal steric hindrance; tertiary halides are wrong because they are too bulky for backside attack.
