The mechanism of $S_{N} 1$ reaction is given as: A student writes general characteristics based on the given mechanism as:
1 (A) and (B)
2 (A) and (C)
3 (A), (B) and (C)
4 (B) and (D)
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.

Which of the following compounds will produce a precipitate with $\mathrm{AgNO}_{3}$ ?
1
2
3
4
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 $\mathrm{AgNO}_{3}$. (a) (B) (c) (d) So, only produces a precipitate of $\mathrm{AgBr}$ with $\mathrm{AgNO}_{3}$ solution.
