Question 7 of 15

8. The correct increasing order of the reactivity of halides for S_N1 reaction is:

PhCH₂ – X < (CH₃)₂CH – X < CH₃ – CH₂ – X < CH₂ = CH – CH₂ – X

CH₂ = CH – CH₂ – X < PhCH₂ – X < (CH₃)₂ CH – X < CH₃ – CH₂ – X

CH₃ – CH₂ – X < (CH₃)₂CH – X < CH₂ = CH – CH₂ – X < PhCH₂ – X

(CH₃)₂CH – X < CH₃ – CH₂ – X < CH₂ = CH – CH₂X < PhCH₂ – X
