The balanced chemical equations for the two described reactions are to be written. Concept Introduction: Chemical equations having an equal number of atoms of each type on both sides are known as a balanced chemical equation. For balancing a chemical equation, reactants and products are multiplied by coefficients. The steps to balance chemical equation are: If there is an element that occurs in only one compound on both sides of the equation, balance it first. If there are more than one such element is there, balance metals before non-metals. If the element is present in a free state on both the sides of the equation, balance it last. These elements are balanced by adjusting the coefficients. If coefficients are present in a fraction, convert it into whole numbers by multiplying with the appropriate number.

How many signals do you expect in the H NMR spectrum for this molecule?
Br Br
Write the answer below.
Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H
atoms that would contribute to the same signal as the H already highlighted red
Note for advanced students: In this question, any multiplet is counted as one signal.
