Are molecular orbitals stronger and more stable than atomic orbitals?
Molecular orbitals are generally stronger and more stable than atomic orbitals when they result from the constructive interference of atomic orbitals, leading to bonding molecular orbitals. This stabilization occurs because bonding molecular orbitals lower the energy of the system when atoms combine. Conversely, antibonding molecular orbitals, formed from destructive interference, are higher in energy and less stable than atomic orbitals. Overall, the strength and stability of molecular orbitals depend on their type (bonding vs. antibonding) and the nature of the atomic orbitals involved.
What is the type and how many molecular orbitals of ethylene?
Ethylene (C₂H₄) has a total of 6 molecular orbitals formed from the combination of 2 carbon atomic orbitals and 4 hydrogen atomic orbitals. These consist of 2 bonding molecular orbitals (σ and π) and their corresponding antibonding orbitals (σ* and π*), resulting in a total of 4 occupied molecular orbitals. The σ molecular orbitals include one from the C-C bond and two from the C-H bonds, while the π molecular orbital arises from the overlap of the p orbitals on the carbon atoms.
What is the difference of dicentric and polycentric molecular orbitals?
Dicentric molecular orbitals have two centers of electron density, typically involving two nuclei, while polycentric molecular orbitals involve multiple centers of electron density associated with three or more nuclei. In dicentric orbitals, the electron distribution is primarily influenced by two atoms, whereas in polycentric orbitals, the electron cloud is influenced by multiple atoms, leading to more complex bonding scenarios. This distinction affects the shapes, energies, and bonding characteristics of the resulting molecular orbitals.
What species have no electrons in anti bonding 2p molecular orbitals?
The species that have no electrons in antibonding 2p molecular orbitals are those that have filled 1s and 2s orbitals, but empty 2p orbitals. Examples include beryllium (Be) and boron (B) atoms.

Indicate how bonding is explained in term of molecular orbitals?
When two atoms combine, the overlap of their atomic orbitals produces molecular orbitals. An atomic orbital belongs to a particular atom, whereas a molecular orbital belongs to a molecule as a whole. Much like an atomic orbital, two electrons are required to fill a molecular orbital. A bonding orbital is a molecular orbital occupied by the two electrons of a covalent bond
What is the difference between bonding and anti bonding molecular orbital?
Electrons in a bonding orbital have lower energy levels than the average energy of a valence electrons in the isolated atoms between which the orbital is formed. Antibonding orbitals do not meet this criterion, so that anitbonding orbitals can be stable only in conjunction with bonding orbitals, whereas bonding orbitals can be formed without any accompanying antibonding orbitals.The molecular orbitals which is formed by the addition of atomic orbitals is called bonding molecular orbitals.The molecular orbitals which is formed by the subtraction of atomic orbitals is called antibonding molecular orbitals.

A new set of identical orbitals formed by combining the atomic orbitals of an atom involved in covalent bonding?
Molecular orbitals are formed by the overlap of atomic orbitals from different atoms in a covalent bond. These molecular orbitals have distinct shapes and energies compared to the atomic orbitals they are formed from. The number of molecular orbitals formed is equal to the number of atomic orbitals that combine.

How atoms are combined to form molecule?
Through the sharing of electrons in molecular orbitals.
How is a molecular orbital formed?
In molecular orbital theory, MO theory, molecular orbitals are "built" from atomic orbitals. A common approach is to take a linear combination of atomic orbitals (LCAO), specifically symmetry adapted linear combinations (SALC) using group theory. The formation of a bond is essentially down to the overlap of the orbitals, the orbitals being of similar energy and the atomic orbital wave functions having the correct symmetry.
What is the difference between non-bonding and antibonding orbitals in molecular chemistry?
Non-bonding orbitals are electron orbitals that do not participate in bonding between atoms, while antibonding orbitals are electron orbitals that weaken or oppose the formation of chemical bonds between atoms.
What species have no electrons in anti bonding 2p molecular orbitals?
The species that have no electrons in antibonding 2p molecular orbitals are those that have filled 1s and 2s orbitals, but empty 2p orbitals. Examples include beryllium (Be) and boron (B) atoms.

How do co molecular orbitals contribute to the bonding and electronic structure of a molecule?
Co molecular orbitals are formed when atomic orbitals from two or more atoms overlap and combine. These orbitals contribute to the bonding and electronic structure of a molecule by allowing electrons to move freely between the atoms, creating a stable bond. The sharing of electrons in co molecular orbitals helps determine the strength and properties of the bond, as well as the overall shape and reactivity of the molecule.
