Compare the boiling points of the various isomeric hydrocarbons shown in the table below. Notice the relationship between boiling point and structure; branched-chain hydrocarbons have lower boiling points than the unbranched isomer. Speculate on possible reasons for this trend. Why might the intermolecular forces be slightly different in these compounds? Compound Boiling Point (°C) 68.9 Hexane 3-Methylpentane 2-Methylpentane 2,3- A Dimethylbutane 2,2- 63.2 60.3 58.0 49.7 Dimethylbutane O The more branched structure has smaller exposed surface and hence stronger dispersion intermolecular forces. The more branched structure has smaller exposed surface and hence weaker dispersion intermolecular forces. O The more branched structure has larger exposed surface and hence weaker dispersion intermolecular forces. O The more branched structure has larger exposed surface and hence stronger dispersion intermolecular forces.

What is the difference between optical activity/polarimetry vs. (R)/(S) configurations? (+) seems to be clockwise, while (-) seems to be counterclockwise. (R) seems to be clockwise when the lowest priority group is facing the back, while (S) seems to be counterclockwise. Does (R) match up with (+) and (S) match up with (-)? If not, what is the difference? Is it that (R) and (S) are just how we determine the priorities in space while (+) and (-) can be determined via labaratory experiments? How can (R)(-) or (S)(+) exist then? Would this show that the spatial arrangement is incorrect in comparison with what the polarimeter shows?

Draw the skeletal (line-bond) structure for (5S), (3Z)-5-chlorohex-3-en-2-one. Use a dash or wedge bond to indicate stereochemistry of substituents on asymmetric centers, where applicable. Show proof for (5S) and (3Z).
FUNCTIONAL GROUPS The research team on Natural Products Chemistry from De La Salle University-Dasmariñas under Mr. Gab has discovered a novel compound from an endemic Philippine nudibranch, Chromodoris cavitensis, whichinhabits the coral reef system near Caylabne Bay in Ternate, Cavite. Exhaustive analysis has revealed acomplex structure as shown below which they aptly named as “chromocavitenin”. Initial tests revealed that thiscompound has potent anti-carcinogenic properties. Encircle and identify the 13 distinct functional groups that arepresent in chromocavitenin.
