The highest energy occupied molecular orbital in the C-C bond of the C₂ molecule is 2pπ orbitals.
<h3>What is Molecular Orbital Theory?</h3>According to this theory,
- Molecular orbitals are formed by intermixing of atomic orbitals of two or more atoms having comparable energies
- The number of molecular orbitals formed is equal to the number of atomic orbitals combined.
- The shape of molecular orbitals formed depends on the type of atomic orbitals combined
- Only atomic orbitals having comparable energies and the same orientation can intermix
- Bonding M.O. is formed by the additive effect of atomic orbitals and thus, has lower energy and high stability.
- Antibonding M.O. is formed by the subtractive effect of atomic orbitals and thus, has higher energy and low stability.
- Bonding M.O. is represented by
while Antibonding M.O. is represented by

Answer : The pressure after the temperature change is, 0.752 atm
Explanation :
Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.
or,
where,
= initial pressure = 0.82 atm
= final pressure = ?
= initial temperature =
= final temperature =
Now put all the given values in the above equation, we get:
Thus, the pressure after the temperature change is, 0.752 atm
