Question

Plots for $2s$ orbitals are:

$X,Y$ and $Z$ are respectively

• A. $\psi$, ${\psi }^2$, $4\pi {\psi }^2{r}^2$,
• B. ${\psi }^2$,$4\pi {\psi }^2{r}^2$,$\psi$
• C. $4\pi {\psi }^2{r}^2$, ${\psi }^2$, $\psi$
• D. ${\psi }^2$, $\psi$, $4\pi {\psi }^2{r}^2$

Answer 1

The correct option is D ${\psi }^2$, $\psi$, $4\pi {\psi }^2{r}^2$

$X$ is Probability density ${\psi }^2$ and r is the distance from the nucleus
$Y$ will be Wave function $\psi$ because value of $r$ cannot be negative.

So,$Z$ will be $4\pi {\psi }^2{r}^2$. $Z$ represents radial probability function
