Which of the following `MOs` has more than one nodal plane?

Options

A. `pi 2p_(y)`
B. `sigma 2s`
C. `pi^(**) 2p_(y)`
D. `sigma^(**) 2p_(z)`

Answer

C

Explanation

(a) `pi 2p_(y) implies` one nodal plane
(b) `sigma 2s implies` zero nodal plane
(c ) `pi^(**) 2p_(y)` implies two nodal planes
(d) `sigma^(**) 2p_(z)` implies one nodal plane
