Number of moles of AgCl formed in the following reaction is _____.

This reaction involves the precipitation of silver chloride from an organic molecule when treated with silver nitrate. The number of moles of formed depends on the reactivity of each chlorine atom, specifically their ability to leave and form a stable carbocation.

In the given molecule, we have four different chlorine environments:

• Vinylic Chlorine: Attached to a double bond; unreactive because the C-Cl bond has partial double-bond character due to resonance.
• Aromatic (Chlorobenzene) Chlorine: Directly on the benzene ring; unreactive because of the strong sp2 C-Cl bond and resonance.
• Benzylic Chlorine: On the carbon adjacent to the ring. This is highly reactive because the resulting carbocation is resonance-stabilized by the benzene ring.
• Tertiary Chlorine: On the far right. This is also reactive because it forms a stable carbocation.
