Complete Table 3.1.
The bond energy values in Table 3.1 are for the $X$-$X$ bond, where $X$ stands for the halogen. Explain the pattern in the strength of the $X$-$X$ bond in the halogens.
Explain, using an equation, how chlorine, $\text{Cl}_2$, is used in water purification. State the function of the active species produced.
Identify the sodium halide that reacts with concentrated $\text{H}_2\text{SO}_4$ to produce $\text{H}_2\text{S}$.
Identify the sodium halide that undergoes only a Brønsted-Lowry acid-base reaction with concentrated $\text{H}_2\text{SO}_4$.
A student adds a few drops of $\text{AgNO}_3\text{(aq)}$ to a solution of $\text{NaBr(aq)}$. State what you see.
Identify every intermolecular force present between molecules of $\text{IBr}$.
Name the mechanism involved in the reaction of $\text{IBr}$ with propene.
The reaction of $\text{IBr}$ with propene gives two structural isomers. Draw the two structural isomers shown by these molecules.
Identify the type of structural isomerism shown by the molecules in (d)(iii).
Explain why the two structural isomers do not form in equal amounts.
