Vedclass · Answer

(A) $1$. Angular nodes are equal to the azimuthal quantum number $(l)$. For $d$-orbitals,$l=2$,so they have $2$ angular nodes. Thus,$A$ matches $P$ $(4d_{x^2-y^2})$.$2$. The $d_{z^2}$ orbital has zero nodal planes (it has two conical nodal surfaces). Thus,$B$ matches $Q$ $(3d_{z^2})$.$3$. Radial nodes are calculated by the formula $(n - l - 1)$. For $3s$,$n=3, l=0$,so radial nodes $= 3-0-1 = 2$. Thus,$C$ matches $S$ $(3s)$.$4$. Angular nodes for $f$-orbitals are $l=3$. Thus,$D$ matches $R$ $(4f)$.Therefore,the correct match is $A-P, B-Q, C-S, D-R$.
