hi , my questions is
consider H3CNO molecule:
1) what is the hybridization of the carbonm nitrogen, and oxygen.

2) which atom (s) is (are ) lewise base (s)?

in (1) in know that to know the hybridization of the atom you must count the number of group arounde the atom , but here N have only 1 group so how can i know the hybridzatio.

in (2) i think that lewis base is the atom that can donate electron so i think of O  and N  as lewis base is that right?

To find the hybridization you need to count the regions of electron density surrounding atoms.  So also remember that lone electron pairs take up space and need to be counted as well, but only as one region.  Also double and triple bonds are counted as one region each.

As for the Lewis Base; these are electron pair donors and Lewis Acids are electron pair acceptors.

Hope it helps.

thanks nate , but i still don't know how to get the hybridization of the nitrogen atom??
