Question

1. the N - C₂ - C₁ bond angle is 109.5°
2. the geometric shape around carbon 2 is trigonal pyramidal
3. this molecule has two pi bonds
4. both carbon 1 (carboxyl carbon) and 2 have the same hybridization
5. this molecule is non polar

Answer 1

1. the N - C₂ - C₁ bond angle is 109.5° - TRUE
2. the geometric shape around carbon 2 is trigonal pyramidal - FALSE. It would be tetrahedral
3. this molecule has two pi bonds - FALSE. It has 1 pi bond
4. both carbon 1 (carboxyl carbon) and 2 have the same hybridization - FALSE. C1 is sp² , C2 is sp³
5. this molecule is non polar - FALSE. The molecule is polar
