Valence Matching

Hybridization and Bonding

For each of the six structural formulas (A through F), shown below, five questions are posed. The answer to each is a number that should be entered in the appropriate answer box.
Note that the sigma-bond question refers only to carbon-carbon bonds, whereas the pi-bond question includes all such bonds between carbon and any other kind of atom.
