Which of the following statements accurately describes the difference between a sigma (σ) and a pi (π) bond? A. Pi bonds form from the side-to-side overlap of hybridized sp, sp^2, sp^3 superscript orbitals. B. Sigma bonds form from the end-to-end overlap of two hybridized s or p orbitals. C. The maximum number of σ versus π bonds between two atoms are different, but the energy level of the two bonds are the same. D. Only sigma bonds use hybridized orbitals to overlap in forming the b...
