During a nucleophilic substitution reaction, the rate-determining step involves bond cleavage. Which carbon-halogen bond requires the least energy to break in alkyl halides?
Q1. During a nucleophilic substitution reaction, the rate-determining step involves bond cleavage. Which carbon-halogen bond requires the least energy to break in alkyl halides?
Answer: C-I bond
Explanation: C-I has the lowest bond energy (238 kJ/mol) making it most reactive. C-F is tempting due to high polarity but is strongest.
