The reaction of carbon tetrachloride with water vapor at $500\,^oC$ gives .................

Choose the false statement from the following about $S_N1$ reaction mechanism.

The following reaction,$(CH_3)_3CBr + H_2O \rightarrow (CH_3)_3COH + HBr$,is an example of:

The $S_{N}2$ reaction mechanism proceeds through ........

$A$ bottle containing $C_6H_5I$ and $C_6H_5CH_2I$ has lost its label. To identify them,samples $A$ and $B$ are taken in separate test tubes and boiled with $NaOH$ solution. Finally,the solution in each test tube is acidified with dilute $HNO_3$ and then a few drops of $AgNO_3$ solution are added. Substance $B$ gives a yellow precipitate. Which statement is correct for this process?

What would be the effect of increasing solvent polarity on the rate of each of the following reactions? ($Nu =$ neutral nucleophile)
$A. Nu + R-L \to Nu^{+}-R + L^{-}$
$B. R-L \to R^{+} + L^{-}$
