Answer to Question #254775 in Physical Chemistry for Kartik

Question

If A and B are two atoms bonding along tha z-axis, predict giving reason which of the following orbitals can combine :

1. 1s and 2s

Answer 1

π bonds occur when two (unhybridized) p-orbitals overlap. The p-orbitals, in one π bond, are located above and below the nuclei of the atoms. By occupying the region of space that is above, below, and on the sides of an atom's nuclei, two π bonds can form.
