Question

The given diagram shows point `P_(1),P_(2)P_(3)&P_(4)` in 1s orbital.

The correct oreder of increasing radial probability at these point are
A. `P_(1)=P_(2)=P_(4)gtP_(3)`
B. `P_(1)=P_(3)ltP_(2)=P_(4)`
C. `P_(1)=P_(3)gtP_(2)=P_(4)`
D. `P_(1)=P_(2)=P_(4)ltP_(3)`

Answer 1

Correct Answer - C
`Psi^(2)(r)` 1 s orbital do not depend upon angular part ,`therefore p_(1)=p_(3)`
and decrease with increase in distance from the nucleus , therefore `P_(2)ltP_(3)`
