Question

Q. Anti-bonding molecular orbital is formed by
1) Addition of wave functions of atomic orbitals
2) Substraction of wave functions of atomic
orbitals
3) Multiplication of wave functions of atomic
orbitals
4) Finding the arthemetic mean

​

Answer 1

Answer:

1Addition of wave functions of atomic orbitals

Explanation:

Anti-Bonding orbitals are essentially the "opposite" of bonding orbitals. They are formed when atomic orbitals combine in ways that lead to predominantly destructive interference. The key feature of anti-bonding orbitals is that the molecular orbitals have a higher energy then the corresponding atomic orbitals.

Answer 2

1) Addition of wave functions of atomic orbitals
