4.Chemical Bonding and Molecular Structure
hard
Which of the following $M.O$ has two nodal Plane's
A
${\sigma _{2s}}$
B
${\pi _{2{p_y}}}$
C
${\pi ^ * }_{2{p_y}}$
D
${\sigma ^ * }_{2{p_z}}$
Solution
In the given figure, bonding and antibonding orbital are shown for $p _{ x }$ orbital.
Similar overlapping of $p_y$ orbitals take place.
Therefore, $\pi^* 2 p _{ y }$ antibonding molecular orbital has two nodal planes.
