Question

3. Do all parts: a. What is the most likely molecular formula of a compound (that contains only C, H and O) which has a molecular ion in the EI mass spectrum with m/z of 104 and an M+1 peak that is 5.5% of the intensity of the molecular ion peak? (4 points) b. What is the most likely molecular formula of a compound that has a molecular ion in the EI mass spectrum with m/z of 136, with a M+1 and M+2 peaks that are 4.4% and 49% of the intensity of the molecular ion peak, respectively. (4 points) c. Treatment of the alkyne (A) under hydroboration-oxidation reaction conditions produce ketones B and C. Provide a detail account as to how these two compounds could be identified with Mass Spectrophotometry. Detail fragmentation are necessary for consideration for full points (12 points) A 1. BH3 2. HOOH, NaOH O B + O C
