Options:
  • A Sigma bonds have parallel atomic orbitals, while pi bonds have perpendicular atomic orbitals.
  • B Sigma bonds have perpendicular atomic orbitals, while pi bonds have parallel atomic orbitals.
  • C Sigma and pi bonds have the same orientation of atomic orbitals.
  • D Sigma bonds have spherically symmetrical atomic orbitals, while pi bonds have saucer-type charged clouds.

The correct answer is: Sigma bonds have parallel atomic orbitals, while pi bonds have perpendicular atomic orbitals.
The Sigma (σ) bonds are formed by head-on overlap with parallel atomic orbitals, while pi (π) bonds have atomic orbitals that overlap sidewise with their axes perpendicular to each other.
