Problem

Azo dyes are organic dyes that are used for many applications, such as the coloring of fabrics. Many azo dyes are derivatives of the organic substance azobenzene, C12 H10 N2. A closely related substance is hydrazobenzene, C12 H12 N2. The Lewis structures of these two substances are showin in the diagram. The structure of Azobenzene is two Ns double bonded to one another; each is single bonded out to benzene and has one pair of dots.  In hydrazobenzene, the Ns are instead single bonded to each other and below to H. (Recall the shorthand notation used for organic molecules.)

Predict the N-N-C angles in each of the substances.
