Question

Correct statement(s) regarding $3p_y$ orbital is/are :

• A. angular part of wave function is independent of angles$\left(\theta and\varphi \right)$
• B. no. of maxima when a curve is plotted between $4\pi r^{2\left(r\right)}$ vs r are '2'
• C. 'xz' plane acts as nodal plane
• D. magnetic quantum number must be '-1'

Answer 1

Answer: (B), (C)

The correct options are
B no. of maxima when a curve is plotted between $4\pi r^{2\left(r\right)}$ vs r are '2'
C 'xz' plane acts as nodal plane

As $3p_y$ has 2 node, one is radial and one is angular, and for $p_y$, xz plane acts as nodal plane.
