- 16-17 Propylamine (bp 48°C), ethylmethylamine (bp 37°C), and trimethylamine (bp 3°C) are constitutional isomers with the molecular formula C3HgN. Account for the fact that trimethylamine has the lowest boiling point of the three and propylamine has the highest.arrow_forwardLinolenic acid (Table 10.2) and stearidonic acid are omega-3 fatty acids, unsaturated fatty acids that contain the first double bond located at C3, when numbering begins at the methyl end of the chain. Predict how the melting point of stearidonic acid compares with the melting points of linolenic and stearic acids. A current avenue of research is examining the use of soybean oil enriched in stearidonic acid as a healthier alternative to vegetable oils that contain fewer degrees of unsaturation.arrow_forwardAnswer the following questions by referring to the ball-and-stick model of fentanyl, a potent narcotic analgesic used in surgical procedures. a. Identify the functional groups. b. Label the most acidic proton. c. Label the most basic atom. d. What types of intermolecular forces are present between two molecules of fentanyl? e. Draw an isomer predicted to have a higher boiling point. f. Which sites in the molecule can hydrogen bond to water? g. Label all electrophilic carbons.arrow_forward
