“Explain why 2-iodo-2-methylpropane gives a precipitate instantly with AgNO₃(aq), but 1-iodopropane takes several minutes.” Model Answer: “2-iodo-2-methylpropane is tertiary, so it undergoes SN1 reaction via a stable carbocation, leading to rapid release of I⁻ ions. 1-iodopropane is primary and must undergo slower SN2 reaction, requiring backside attack before I⁻ leaves.” Excess concentrated ammonia in ethanol (under pressure in
