Part 1- Intermolecular Force Interactions 1) Why is boiling point of a straight chain hydrocarbon in general higher than a branch hydrocarbon of the same molecular formula? 2) Hydrogen bonding is a strong intermolecular interaction that can cause atoms to pair and remain together as dimolecular species in both liquid and gas phases. Each of the following compounds exhibits this behavior. Draw the structure for each molecular diatomic using dotted-lines to indicate the hydrogen bonding interaction. a) HF b) CH 3 OH (cyclic in dimolecular form) 3) The following 3 substances are derivatives of molecules used in the production of analog videotape. C C C C O C O O H H H H C C C C O C O H H H H H H C C C C O C H O H H H a) Which of these compounds can form H bonds? Draw structures in each case for those who can. b) Hydrogen bonding can also be “intramolecular” or within the same molecule. This takes the form of a polygon with atoms as corners and bonds as sides and a hydrogen bond as one of the sides. Which of these molecules is likely to form a stable internal H
