Choose the member of each pair that will react faster by the \(S_N1\) mechanism.
(a) 1-bromopropane or 2-bromopropane
(b) 2-bromo-2-methylbutane or 2-bromo-3-methylbutane
(c) n-propyl bromide or allyl bromide
(d) 1-bromo-2,2-dimethylpropane or 2-bromopropane
(e) 2-iodo-2-methylbutane or tert-butyl chloride
(f) 2-bromo-2-methylbutane or ethyl iodide
Step 1 of 6
The structure that can form the more stable carbocation will undergo SN1 mechanism faster
(a) 1-bromopropane or 2-bromopropane
2-Bromopropane will react faster by the SN1 mechanism than 1-bromopropane because secondary alkyl halide while 1-Bromopropane is primary alkyl halide .In general ,secondary alkyl halides are more favourable for SN1 reaction than primary alkyl halides .
