The alkyl halide that undergoes SN1 reaction more readily is

Question

The alkyl halide that undergoes SN1 reaction more readily is (A) ethyl bromide (B) iso-propyl bromide (C) vinyl bromide (D) n-propyl bromide

SN1 mechanism involves formation of carbocation intermediate. Hence, the species which gives the most stable carbocation readily undergoes SN1 mechanism, t-butyl bromide gives the most stable carbocation, i.e., 3° carbocation, so it readily undergoes SN1 reaction.

Q. The alkyl halide that undergoes $S_{N} 1$ reaction more readily is

ethyl bromide

iso-propyl bromide

vinyl bromide

n-propyl bromide

$S_{N} 1$ mechanism involves formation of carbocation intermediate. Hence, the species which gives the most stable carbocation readily undergoes $S_{N} 1$ mechanism, t-butyl bromide gives the most stable carbocation, i.e., $3^{\circ}$ carbocation, so it readily undergoes $S_{N} 1$ reaction.
