The hydrogen atomic orbital given by $N r^{2} e^{\frac{-r}{3 a_{0}}}\left(3 \cos ^{2} \theta-1\right)$ represents

(a)$2 p$ orbital

(b)3p orbital

(c)3d orbital

(d)4d orbital

Answer

Answer: C ✓ checked by 4AB · confidence high

Explanation

r² gives l = 2 and e^(−r/3a₀) gives n = 3; (3cos²θ − 1) is the dz² angular part — 3d (c).
