• 3-Methylpentane is a colourless liquid with a characteristic
smell that reacts with bromine liquid (a diatomic molecule) in the
presence of a catalyst. A bromo-3-methylpentane liquid compound is
formed through the substitution of one hydrogen with bromine. Write
a balanced chemical equation for this reaction and explain if it
requires balancing. Hydrogen bromide gas is also a product of this
chemical reaction. Note: ignore the presence of the catalyst. •
b.Bromo-3-methylpentane has three isomers: 1-Bromo-3-methylpentane,
2-Bromo-3-methylpentane, 3-Bromo-3-methylpentane. Draw the skeletal
formula of the isomers and write the chemical formula for each
isomer. • c.In any manufacturing process, reaction monitoring
ensures that a chemical reaction proceeds as expected. Table 1
shows the monitoring data for the formation of bromo-3-methyl
pentane, collected using a technique called gas chromatography.
Note that the concentrations of the Bromo-3-methyl pentane
solutions are given in millimoles per liter (mmol l–1). The
abbreviation mM (millimolar) is frequently used. Plot a graph of
the data in Table 1, and include the graph as your answer to this
question. Table 1 Concentration of Bromo-3-methyl pentane with
time. Elapsed time/hours Concentration of Bromo-3-methyl pentane/mM
0 0 1 20 3 45 5 60 7 70 9 77 11 81 • d.The rate of reaction at all
times is given by the gradient of the concentration-time graph.
Annotate your graph to show how you could determine the rate of
reaction at 5 hours by drawing a tangent to the curve. Include your
annotated graph in the answer and use the values from it to
calculate the rate of reaction at 5 hours. Show your calculation in
full. • e.How many grams of Bromo-3-methyl pentane are there in
0.250 liter of a 30.0 mM solution? Show your calculations in
full.
