1. Using the "octet rule," write the Lewis structures for the following molecules: (a) CH2Cl2 (b) NCl3 (c) CS2 and (d) CH3CHCHCH3 2. The following questions refer to the bolded carbon atom in the molecule: CH3CHCHCH3 a) How many areas of high electron density (number of bonded atoms plus number of lone pairs) surround the indicated C? b) Give the AXmEn notation for the C in this molecule (Look on page 6 of this experiment) c) What is the molecular geometry for the C in this molecule? d) What are the bond angles surrounding C? 3. While obeying the octet rule, nitric acid HNO3, has two resonance structures. Draw them. (Hint: the hydrogen atom is bonded to one of the oxygen atoms).
