Rate of solvolysis of allyl and alkyl halides

Suppose I have 2 compounds, 3-chloropropene and 1-bromo-1-methylcyclohexane. Without knowing the values, how can we compare the rate of solvolysis? My attempt: Resonance is quite dominant character ...

Stability of α-chlorocarbocations

I'm trying to compare the relative stability of two carbocations: $$\ce{CH3-\overset{+}{C}H-Cl}\quad\text{vs}\quad\ce{CH3-\overset{+}{C}H2}$$ Does the $\ce{Cl}$ exert a +M effect to stabilise the ...

Treatment of allylic alcohol with thionyl chloride: why is the product rearranged?

I have read that $\mathrm{S_Ni}$ reactions involving the attack of $\ce{SOCl2}$ on alcohols proceed without the formation of discrete carbocations, and hence there is no rearrangement involved. But ...

Friedel-Crafts Alkylation and hybridization

Why must the alkyl halide be sp3 hybridized with respect to the carbon connected to the halogen for the alkylation to occur? Why, for example, can't we use acetylide with a bromine substituted for ...

The role of halogens in electrophilic aromatic substitution

I'm trying to understand what halogens do in electrophilic aromatic substitution. Consider the following. Bromobenzene is introduced to a carbocation. Bromobenzene will likely react, but at a slower ...
