How many double bonds must be added to give each carbon atom an octet?
How many resonance structures can be drawn for naphthalein, i.e., in how many different ways can the double bonds be placed?
All of the carbon-carbon bonds in naphthalein are about the same length. Use the formula (number of bonds)/(number of bonding regions) to determine the bond order. Then refer to a table of bond lengths to predict the carbon-carbon bond length to the nearest 0.1 angstrom.
