A student argues that the two nitrogens in the compound below are sp? hybridized, but atom a is still more basic than atom b. Is the student correct? Explain. •• -N-CH2CH3 | b CH2CH3 a

I had gotten this one incorrect, but i wanted to use it to study, so please give me the solution to all parts of this question.

Can you show me im trying to determine which portions are sp2 and sp3 so I can determine where ressonance occurs. Like label them so I can understand kind of the way I did, and then the Oxygen part I dont understand either. For instance I labeled a few but I want each C point and then the oxygen bc after doing so im going to use it to determine delocalized lone pairs and localized lone pairs.

x-xo B Draw molecule A. On that drawing include the lone pairs and the curved arrows that would produce resonance structure B.

\Br A. Redraw the bond-line structure of the molecule above on a separate sheet of paper. B. Draw a chair conformation for the molecule. C. Draw the new chair conformation after ring inversion (ring flip). D. Circle the most stable (lowest energy) chair conformation.
