a) Draw the Lewis structure of nitramide with a single bond between the two nitrogen atoms and include formal charges. Are there any resonance structures? If so, please draw these too. Describe the hybridization of the nitrogen atoms.

b) Using the same atom connectivity as above, draw a Lewis structure with a double bond between the two nitrogen atoms, including formal charges and resonance forms if any. Describe the hybridization of the nitrogen atoms.

c) Which structure (a or b) will be planar and why?

d) According to spectroscopic results, the nonplanar structure is preferred. Is this what you would have predicted from the Lewis Dot structure or not? Explain.

Given an aperture of diameter D. When a wave originates from a point at distance (A) the assumption is that the wave front is planar and strikes all points in the aperture simultaneously. In reality the wavefront is spherical and strikes the center of the aperture first and then the ends last
