Put the bonds below in order from least to greatest bond polarity С-Н N-H Н-Br D. Explain how you arrived at your answers to B and C 2. A. For the following Lewis structures, determine the formal charge on all of the atoms in the structure H H O : нно: C-N-H :Cl H-N-C-C-O: :O-N-O Нн н Ш II B. Add up the sum of the formal charges of the atoms in each structure. What do you notice? What is the sum of the formal charges? C. For each atom with a formal charge of zero, compare the number of bonds to the valence of the atom. What do you notice? 3. Nitrous Oxide is used by dentists as an anesthetic (it is sometimes called laughing gas). Draw the Lewis structure for N2O (N is the central atom). How many resonance structures possible? Indicate which resonance structure would be the most stable and why. are
