Question

A $\pi$ bond is formed between two $P_x$ orbitals containing one unpaired electron each, when they approach each other appropriately along the following axis:

• A. $x-axis$
• B. $y-axis$
• C. $z-axis$
• D. any direction

Answer 1

Answer: (B), (C)

$z-axis$
$y-axis$

As Px orbitals are lying along x-axis,they will form pi bond along the axis which are perpendicular to x-axis (y or z axis).
