The correct increasing order of the reactivity of halides for SN 1 reaction is
CH3- CH2- X<(CH3)2CH= X <CH2= CH-CH2- X< PhCH2- X
(CH3)2CH-X <CH3-CH2- X < CH2= CH - CH2-X < PhCH2-X
PhCH2- X<(CH3)2CH=X<CH3-CH2-X<CH2= CH- CH2- X
CH2= CH - CH2- X < Ph- CH2- X <(CH3)2CH-X <CH3-CH2- X
The major product formed in the following reaction is
CH3CH = CH- CH2OH
CH2=CH- CH2- CH2OH
C.
Halogenated compounds on treatment with aq. KOH form alcohols. The halogen atom is substituted by= OH group.
HerE OH acts as a nucleophile.
