Question

1.-5. Match each pair of compounds on the left and their corresponding melting points (m.p.) or boiling points (b.p.)in to the major reason why they increase. Answers may be repeated. All answers should begin with more 1. Hexane (mp. -95) and cyclohexane (m.p, 6) 2. (2-Octadec-9-enoic acid (oleic acid, m.p. 13) and (E)-octadec-9-enoic acid (elaidic acid, m.p. 45) octadec-9-enoic acidCH(CH2hCH(CH)COH m.p. -49) 3. Butan-1-ol (m.p. -90) and butan-1-amine (CH,(CH,INH 4. Butan-1-amine (b.p. 78) and butan-1-ol (b.p. 118) 5. (0%20 (bp 94) and (CH,CHSe (bp. 108) a weight b. polar bonds c. rotational symmetry d van der Waal interactions e.h 6. Using the estimate that we learned in class, which compound has the closest density to that of water? Assume C 12, H 1, O 16, F 19 a. b. c. d. e.

Explanation / Answer

1. Hexane (m.p -90) and cyclo hexane (m.p 6) -More van Der Waals interactions

2. More rotational symmetry

3. More Hydrogen bonds

4. More polar bonds

5. More weigh
