When two atomic orbitals of comparable energies undergoes constructive interference there is formation of :
Bonding molecular orbital of lower energy as compared to atomic orbital.
Anti-bonding molecular orbital of higher energy as compared to atomic orbital
Bonding molecular orbital of higher energy as compared to atomic orbital.
Anti- bonding molecular orbital of lower energy as compared to atomic orbital.
As we have learnt,
When two atomic orbitals of comparable energies undergoes CONSTRUCTIVE INTERFERENCE there is formation of bonding molecular orbital
of lower energy as compared to atomic orbital.
Hence, option number (1) is correct.
