Which of the following graph represents variation of 2 p -orbital wave function with distance from the nucleus?

Correct answer

0

Step-by-step solution

- The radial wave function of hydrogen-like orbitals depends on principal quantum number ( ( n )) and azimuthal quantum number (l). - For a (2 p ) orbital ((n=2, I=1) ) : - The wave function ( (0)=0 ) (because all p-orbitals have a node at the nucleus). - It rises to a maximum value at some distance from the nucleus. - Then it decays exponentially as (r ). - Therefore, the correct graph must start from 0 at the nucleus, peak once, and then fall off. This matches graph (1).
