Thank you in advance.arrow_forwardPredict the products of this organic reaction: O N IN A N + H2O + HCI ? Specifically, in the drawing area below draw the skeletal ("line") structure of the product, or products, of this reaction. If there's more than one product, draw them in any arrangement you like, so long as they aren't touching. If there aren't any products because this reaction won't happen, check the No reaction box under the drawing area. 田 C + Explanation Check Click and drag to start drawing a structure.

- 6. For each of the following, fill in the synthesis arrows with reagents and show the intermediates. You DO NOT need to use the same number of arrows that are shown (you may use more or less), but the product must be formed from the reactant. Then write the mechanism of one step in the synthesis (you can choose which step to write the mechanism for), including all reagents required, clearly labeling the nucleophile and electrophile for each step, and using curved arrows to show the steps in the mechanism. a. b.
