Question

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 :
A. 2 and 3
B. 1,2,3,4
C. Only 2
D. 1 & 3

Answer 1

Correct Answer - A
for `dx^(2) - y^(2)` orbiral lobes are on xy plane
