Question

The main axis of a diatomic molecule is $z$, molecular orbital $p_x$ and $p_y$ overlaps to form, which of the following orbital:

• A. $\pi -$molecular orbtial
• B. molecular orbital
• C. molecular orbtial
• D. no bond will form

Answer 1

Answer: (A)

$\pi -$molecular orbtial

If $z-$axis is the main axis, it takes part in sigma bonding and orbitals perpendicular to it participate in $\pi -$bonding.

Hence, $P_x$ and $P_y$ orbitals form $\pi$ molecular bonds.
