What is the 3d shape and polarity of 1-amine-1,3-cyclopentadiene?

Answer 1

Here we have an almost planer pentagon (due to the two double bonds in the ring) with an amino (NH₂) group at the number 1-position. NH₂ is quite polar and can form H-bonds with like molecules, so the molecule is polar around the -NH₂ but nonpolar around the rest of the molecule,
