Concept introduction:
Beer’s law – The beer’s law states that the amount of light absorbed by a solution is directly proportional to its concentration. A more concentrated solution absorbs more amount of light. This relation is used to determine the concentration of a chemical species in a solution. This is mainly applicable in the UV-Visible spectroscopy. However, at high concentrations, the deviations from the law are observed.

A student proposes the transformation below in one step of an organic synthesis. There may be one or more reactants missing from the left-hand side, but there
are no products missing from the right-hand side. There may also be catalysts, small inorganic reagents, and other important reaction conditions missing from
the arrow.
• Is the student's transformation possible? If not, check the box under the drawing area.
. If the student's transformation is possible, then complete the reaction by adding any missing reactants to the left-hand side, and adding required catalysts,
inorganic reagents, or other important reaction conditions above and below the arrow.
• You do not need to balance the reaction, but be sure every important organic reactant or product is shown.
