Explanation:

$\mathrm{S}_{\mathrm{N}} 1$ reaction is independent of strength of nucleophiles. Generally strong nucleophiles favored the $\mathrm{S}_{\mathrm{N}} 2$ but in $\mathrm{S}_{\mathrm{N}} 1$ weak nucleophiles are favored.
- Order of stability of alkyl carbocation $\mathrm{R}^{+}$IS $3^{\circ}>2^{\circ}>$ $1^{\circ}$. Bulky carbocation $\left(3^{\circ}\right)$ more stable and forms easily increase the bulkiness of carbocation increase the stability of carbocation.
- In $\mathrm{S}_{\mathrm{N}} 1$, both inversion and retension can takes place in equal ratio gives the racemic mixture if $\mathrm{R}-\mathrm{X}$ is optically active.
- $\mathrm{S}_{\mathrm{N}} 1$ is favorable in polar solvent due to salvation of carbocation increase the stability of carbocation.

Explanation:

The reaction aryl halides with alkyl halides and sodium metal in the presence of dry other to give substituted aromatic compounds.

Explanation:

Only ionic halides $\left(\mathrm{X}^{-}\right)$give precipitate of $\mathrm{AgX}$ with $\mathrm{AgNO}_{3}$ solution. So, an organic bromide able to produce $\mathrm{R}^{+}$(stable carbocation) and $\mathrm{Br}^{-}$in aqueous solution will give precipitate of $\mathrm{AgBr}$ with $\mathrm{AgNO}_{3}$.
