Hey guys! For question 17.33 a the answer key says that the nitrogen atoms each have a lone pair used for bonding, making it tridentate. How would u draw the Lewis structure of this molecule in order to figure out the lone pairs?

The carbons and nitrogens form a long chain, with the hydrogens bonded to each atom. The order in which the atoms are written gives the order of the chain, and because there are two identical segments, the molecule can be drawn as symmetrical. If you count the number of available valence electrons, each nitrogen atom must have a lone pair.
