Identify the product obtained in the following reaction: $CH_3CH_2Br + CH_3COOAg \xrightarrow{\Delta} x + AgBr$

Which of the following is/are the product$(s)$ of the given reaction?
$1$-chloro-$1$-ethyl-$2$-methylcyclohexane $\xrightarrow{C_2H_5O^-K^+ / \Delta}$ ?

Bottles containing $C_6H_5I$ and $C_6H_5CH_2I$ lost their original labels. They were labelled $A$ and $B$ for testing. $A$ and $B$ were separately taken in test tubes and boiled with $NaOH$ solution. The end solution in each tube was made acidic with dilute $HNO_3$ and then some $AgNO_3$ solution was added. Substance $B$ gave a yellow precipitate. Which one of the following statements is true for this experiment?

$S_N1$ reactions are generally carried out in which type of solvents?

Which of the two stereoisomers of $4-t-$butylcyclohexyl iodide $(^{127}I^-)$ will undergo $S_N2$ substitution with $^{128}I^-$ faster,and why?

$A$ solution of $(-)-1-$chloro$-1-$phenylethane in toluene racemises slowly in the presence of a small amount of $SbCl_5$,due to the formation of:
