Which of the following has distorted tetrahedral structure?
Correct answer: B. AsH3
- A. CCl4
- B. AsH3
- C. SiCl4
- D. C2H2
Explanation
Arsine (AsH3) is a molecule containing one arsenic (As) atom and three hydrogen (H) atoms. It has a distorted tetrahedral structure due to the lone pair of electrons on the arsenic atom. This lone pair causes the hydrogen atoms to be pushed slightly closer together, resulting in a slight distortion from a perfect tetrahedral angle. AsH3 exhibits a pyramidal molecular geometry due to the influence of the lone pair.

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.
