Is there an easy and *quick* way to look at a carbon and know what kind of hybridization it has? For some reason I have always struggled with this. Thanks for any and all responses!

In general....a carbon with single bonds is sp3,,,,,,with double bonds sp2,,,,,and triple bonds,,,,,,or two double bonds on a carbon as in CO2 will be sp. Exceptions exist.....be careful of resonance.......but this " trick " should help you.

If there is resonance, how do you determine the hybridization?

Just look at the number of attachments. If 4 attachments, sp3, 3 attachments sp2 and 2 attachments sp.

Ok thank you! So just to make sure, a peptide bond for example would be considered sp3 if I use this method with resonance right?

No. That is sp2 because of double bond.

So with resonance you use the lower hybridization?

So with repsonance you use the lower hybridization?
