The proof that the test tubes contain three different chemical compounds should be given. Also, the minimumnumber of melting points needed to proof that should be determined. Concept introduction: Temperature at which an element changes from the solid state to the liquid state is known as melting point or sometimes liquefaction point. At the melting point, both solid and liquid phase coexist in equilibrium. It depends on the pressure and is normally defined at the standard pressure ( 1 atm ) . Mixed melting point is a techniquethat is used to identify chemical compounds. It is used when a substance of known identity and melting point is mixed with another unknown substance to calculate its melting point.

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. Number of signals in the 'H NMR spectrum. For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in top molecule For the molecule in the bottom drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in bottom molecule

In the drawing area below, draw the major products of this organic reaction: 1. NaOH ? 2. CH3Br If there are no major products, because nothing much will happen to the reactant under these reaction conditions, check the box under the drawing area instead. No reaction.
