Vedclass · Answer

(B) The $3d_{x^2-y^2}$ orbital has lobes along the $x$ and $y$ axes. The electron density is concentrated along these axes,not in the $xy$ plane. Thus,the statement is correct.$(b)$ The $3d_{z^2}$ orbital has lobes along the $z$-axis and a ring of electron density in the $xy$ plane. Thus,the statement that electron density in the $xy$ plane is zero is incorrect.$(c)$ The number of radial nodes is given by $(n - l - 1)$. For $2s$,$n=2, l=0$,so nodes $= 2 - 0 - 1 = 1$. Thus,the statement is correct.$(d)$ For $2p_z$ orbital,the nodal plane is the $xy$ plane (where $z=0$). The $yz$ plane is not a nodal plane for $2p_z$. Thus,the statement is incorrect.Therefore,statements $(b)$ and $(d)$ are incorrect.
