Short Answer, Continued. Write short responses for each of the following questions. Limit text to less than 75 words. In some cases, you are asked to draw structures as part of your answers. (35 points, 5 points each)
d) Draw three structural isomers (aka constitutional isomers) of amides with the formula C3H-NO (3pts). Rank them in terms of melting point (MP), 1= highest MP and 3 = lowest MP (1pt). Explain your ranking (1 pt).
e) Hexafluorobenzene reacts in nucleophilic aromatic substitution (NAS) with strong nucleophiles. If it reacts with NaOCH3, can the reaction easily be stopped after one fluoride undergoes substitution or will the product be more reactive than the starting material? Explain your answer. If it reacts with KCN, can the reaction easily be stopped after one fluoride undergoes substitution or will the product be more reactive than the starting material? Explain your answer.

Modern pennies are composed of zinc coated with copper. a student determines the mass of a penny to be 2.482 g and then makes several scratches in the copper coaling (to expose the underlying zinc). the student puts the scratched penny in hydrochloric acid, where the following reaction occurs between the zinc and the hcl (the copper remains undissolved): zn(s) + 2 hcl(aq) → h2(g) + zncl(aq)the student collects the hydrogen produced over water at 25 °c. the collected gas occupies a volume of 0.899 l at a total pressure of 79 j mmhg. calculate the percent zinc (by mass) in the penny. (assume that all the zn in the penny dissolves.)
