The use of acid-base extractions to purify the heptanoic acid is to be stated and the chart that shows the impurities at each stage is to be given. Concept introduction: Acid-base extraction is the technique that is used to separate the acidic and basic substance from the mixture on the basis of their chemical properties. This technique is used during the work up of a reaction after the synthesis of the compounds, so that the product becomes free from any type of impurities. The acidic or basic substances that are similar in chemical properties are impossible to separate through this method.

Predict the major products of this organic reaction: HBr (1 equiv) cold ? Some important notes: • Draw the major product, or products, of this reaction in the drawing area below. • You can draw the products in any arrangement you like. • Pay careful attention to the reaction conditions, and only include the major products. • Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are enantiomers. • Note that there is only 1 equivalent of HBr reactant, so you need not consider the case of multiple additions.

Question 11 of 18 (1 point) Question Attempt: 3 of 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. 1 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.
