Accepted Answer

>

> [!TLDR]
> Markovnikov's rule governs regioselectivity in HX addition to alkenes (H to the carbon with more H's), while Friedel-Crafts acylation installs an acyl group onto an aromatic ring using RCOCl/anhydrous AlCl₃.
>
> **(a) Markovnikov's Rule:**
> When a protic acid HX (e.g. HBr) adds across an unsymmetrical (double bond carbons have different numbers of H) alkene, the rule states: *the negative part (X) of the addendum attaches to the carbon atom with the fewer hydrogen atoms, while hydrogen attaches to the carbon with more hydrogen atoms.*
