Which of the followig is/are correct?

Options

A. `psi_(A)+psi_(B)` gives bonding molecular orbital.
B. 'sigma_(2s)' is bonding molecular orbital
C. The probability density of finding the electrons in bonding molecular orbital equal to `psi_(A)^(2)+psi_(B)^(2)+2psi_(A)psi_(B)`.
D. Electron density increases between the nuclei of bonding M.O.

Answer

A, B, C, D

Explanation

The bonding molecular orbitals are fomred when the waves are in the same phase.
When the waves of s and `p-` orbitals overlap in the same phase (B).
