Which shape/geometry is found in AX2 when the bond angle is 180°?
Correct answer: E. Linear
- A. Pyramidal
- B. Bent
- C. Triangle
- D. Tetrahedral
- E. Linear
Explanation
Linear molecular shape occurs when atoms are arranged in a straight line, typically resulting from two atoms bonded with no lone pairs on the central atom, leading to a bond angle of 180 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.
