Consider the following statements:
(a) Electron density in the `XY` plane in `3d_(x^(2)-y^(2))` orbital is zero
(b) Electron density in the `XY` plane in `3d_(z^(2))` orbital is zero.
(c ) `2s` orbital has one nodel surface
(d) for `2p_(z)` orbital, `XY` is the nodal plane.
Which of these are incorrect statements :

Options

A. a & c
B. b & c
C. Only b
D. a, b

Answer

D

Explanation

(a) Electron density in the `XY` plane in `3d_(x^(2)-y^(2))` orbital is not zero
(b) Electron density in the `XY` plane in `3d_(z^(2))` orbital is not zero.
(c) `2s` orbital has one nodal surface
(d) For `2p_(z)` orbital, `XY` is the nodal plane.
