Hybridization Problem

The structural formula drawn on the right represents a stable C9H7NO compound. You must determine the hybridization state of each carbon atom in the molecule.

Select a hybridization state:

sp3           sp2           sp

Number of such hybridized carbons?  ........ 


Select a hybridization state, and answer the question on the right by entering an appropriate number in the designated box. Your answer will be evaluated by clicking the Check Answer button.
Once this evaluation appears in the text box at tbe bottom right, clicking the Show Answer button on the right will display a molecular model of the compound here. Hybridization features may be displayed on the model by clicking the buttons beneath it. The model may be moved about with the mouse.
