Draw the Lewis structure of CH₃CCH and then choose the appropriate set of hybridization states for the three central atoms. Your answer choice is independent of the orientation of your drawn structure.

(a) Using the molecular orbital model, write the valence electron configuration for CN and use it to calculate the bond order. Is the species paramagnetic? Bond order = Paramagnetic? (b) Using the molecular orbital model, write the valence electron configuration for CO and use it to calculate the bond order. Is the species paramagnetic? Bond order = Paramagnetic?

Valence bond theory The skeletal structure for methyleneimine (CH₂NH) is shown. Draw for yourself the best Lewis structure. Propose a bonding scheme by indicating the hybridization of the central atoms and the orbital overlaps for each bond. (a) H one (b) H-C-N-H The bond labeled (a) forms from The bond labeled (b) forms from: ● one o-overlap of a C (c) π-overlap (s) of a C -overlap of a C sp2 orbital and a N orbital and a N orbital and a H 1s The ideal bond angle <(C-N-H) around the N atom is orbital, and orbital. The bond labeled (c) forms from O - overlap of a N There is/are one lone pair(s) around the N atom. Lewis structures do not attempt to portray 3D shape, but you can predict the molecular geometry from VSEPR theory. The ideal bond angle <(H-C-H) around the C atom is 120 orbital and a H 1s degrees. orbital. degrees. orbital.

(a) Describe the hybridization of the central atom of a molecule with a see-saw shape. (b) Describe the hybridization of the central atom of a molecule with a trigonal planar shape. (c) Describe the hybridization of the central atom of a molecule with a trigonal bipyramidal shape.
