Q2a Borazine is prepared by the reaction of ammonia with diborane? Explain the chemical reaction? b) draw out the resonance structure of borazine?

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.
