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.


A Number of sp3 carbons:  ...............  
Number of sp2 carbons:  ...............  
Number of sp carbons:  ................  
Number of carbon-carbon σ-bonds: .......  
Number of π-bonds to carbon:  .............  
    B Number of sp3 carbons: ...............  
Number of sp2 carbons:  ...............  
Number of sp carbons:  ................  
Number of carbon-carbon σ-bonds: .......  
Number of π-bonds to carbon:  .............  
    C Number of sp3 carbons: ................
