Which specific structural feature characterizes the transition state of an SN2 reaction involving a primary alkyl halide and a hydroxide ion?
Q1. Which specific structural feature characterizes the transition state of an SN2 reaction involving a primary alkyl halide and a hydroxide ion?
Answer: Pentacoordinate transition state
Explanation: SN2 involves a single-step transition state where the carbon is bonded to five groups (pentacoordinate), showing 100% inversion of configuration.
