Question 3 (10 points). What is your best guess for a structure with M+=132 and [M+1]+10.1% of M+and [M+2]+0.69% of M+that contains 02 oxygen or nitrogen atoms and as many carbons and hydrogen as required. - A) Use the rule of 13 (described in class, in a module, but not in the book) to come up with seven speculative formulas, circle your best guess, show all of your work. - B) compute the degree of unsaturation for your seven formulas. - C) Circle your favored formula, and then generate FIVE plausible structures based on your formula Question 4 (10 points). What is your best guess for a different structure with M+=140 and [M+1]10.29% of M and [M+2]0.67% of M that contains 0-2 oxygen or nitrogen atoms and as many carbons and hydrogen as required. - A) Use rule of 13 to come up with Five empirical formulas, circle your best two
