- The boiling point of methylcyclohexane (C7H14, MW 98.2) is 101°C. The boiling point of perfluoromethylcyclohexane (C7F14, MW 350) is 76°C. Account for the fact that although the molecular weight of perfluoromethylcyclohexane is over three times that of methylcyclohexane, its boiling point is lower than that of methylcyclohexane.arrow_forwardAn ion with a positively charged nitrogen atom in a three-membered ring is called an aziridinium ion. The following aziridinium ion reacts with sodiummethoxide to form compounds A and B: If a small amount of aqueous Br2 is added to A, the reddish color of Br2 persists, but the color disappears when Br2 is added to B. When the aziridinium ion reacts with methanol, only A is formed. Identify A and B.arrow_forward16-17 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_forward

W and X are each chiral. W reacts readily in water to form a chiral substitution product Y, CgH17OH. Reaction of a single enantiomer of W produces a single enantiomer of Y as the only substitution product. X likewise reacts readily in water though at a slower rate than W; a chiral substitution product Z, C8H₁7OH, is again formed. Unlike w, however, reaction of a single enantiomer of X produces Z that is nearly racemic. Propose structures for W and X. 0 • Do not use stereobonds in your answer. In cases where there is more than one possible structure for each molecule, just give one for each. • Draw one structure per sketcher.
