BITSAT Chemistry Question (2023) — Solution

Question

The probability density plots of 1 s and 2 s orbitals are given in figure. The density of dots in a region represents the probability density of finding electrons in the region. On the basis of above diagram which of the following statements is incorrect?

Options

  1. A. 1 s and 2 s orbitals are spherical in shape.
  2. B. The probability of finding the electron is maximum near the nucleus.
  3. C. The probability of finding the electron at a given distance is equal in all directions.
  4. D. The probability density of electrons for 2 s orbital decreases uniformly as distance from the nucleus increases.

Answer

D. The probability density of electrons for 2 s orbital decreases uniformly as distance from the nucleus increases.

Step-by-step solution

The probability density of electrons in 2 s orbital first increases then decreases and after that it increases again as distance increases from nucleus.
