Question

If x-axis is the molecular axis, then $\pi$-molecular orbitals are formed by the overlap of:

• A. $s+p_z$
• B. $p_x+p_y$
• C. $p_z+p_z$
• D. $p_x+p_x$

Answer 1

Answer: (C)

$p_z+p_z$

If x-axis is the molecular axis, then $\pi$-molecular orbitals are formed by the overlap of $p_z+p_z$. It is formed by the orbitals in the perpendicular plane to x-axis.
