I. List all the IMFS that are present in a pure sample of substance A below. The Lewis structure of a molecule is shown. H -C C-H | | H II. Draw one example of substance A acting as a H-bond donor with water. Make sure your H- bond starts and ends in the right places. If the molecule can't act as a H-bond donor, write "not possible." II. Draw one example of substance A acting as a H-bond acceptor with water. Make sure your H-bond starts and ends in the right places. If the molecule can't act as a H-bond acceptor, write "not possible." IV. List all the IMF that are present in a pure sample of substance B below. The Lewis structure of a molecule is shown. H H. C N. H H. H V. Compare substance A and substance B. Which would you expect to have the highest boiling point? Briefly explain why (in about 1 sentence). IIC- :O:
