Question

Identify the incorrect statements-

• A. An electronic wave function must be symmetrical with respect to the interchange of any two electrons
• B. Y² must remain unchanged when the spin and space coordinates of the paired electrons are interchanged
• C. For an n electron system the wave function Y will be a function of 3 n spatial coordinate
• D. Anti symmetrical wave function are found to represent the properties of electron.

Answer 1

Answer: (A)

An electronic wave function must be symmetrical with respect to the interchange of any two electrons

Answer 2

Pauli's exclusion principle states that Y² must remain unchanged by interchange of spin and space coordinate and that is possible only if y changes its sign (antisymmetrical).
