The structure of primary amines is:
Correct answer: B. Tetrahedral pyramidal
- A. Trigonal
- B. Tetrahedral pyramidal
- C. Planar
- D. Linear
- E. Regular tetrahedral
Explanation
Tetrahedral pyramidal molecular shape, often referred to as trigonal pyramidal, occurs when a central atom is bonded to three other atoms and has one lone pair of electrons, resulting in a three-dimensional shape with bond angles of approximately 107 degrees

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
