What is atomic and molecular orbital?

The major difference between atomic and molecular orbitals is that atomic orbitals represent electron density in space associated with a particular atom. Molecular orbitals are associated with the entire molecule, meaning the electron density is delocalized (spread out) over more than one atom.

What is meant by molecular orbitals?

A molecular orbital (or MO), in chemistry, refers to an orbital in atomic structure of molecules. It is a wave-function of a molecule’s electron and is used to calculate its chemical and physical properties.

What are atomic orbitals?

In atomic theory and quantum mechanics, an atomic orbital is a mathematical function describing the location and wave-like behavior of an electron in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom’s nucleus.

What is the difference between atomic orbitals and electrons?

Atomic orbital is the wavefunction of the electron at a certain state determined by the quantum numbers. Electron orbit does not exist in Quantum Mechanics.

What is the difference between atomic orbital and molecular orbital Class 11?

The main difference between these two orbitals is that the atomic orbital contains electrons which are influenced by one positive nucleus , whereas in case of molecular orbitals, it contains electrons which are influenced by more than two nuclei depending upon the number of atoms in a molecule.

What are molecular orbitals with examples?

The simplest molecular orbitals are the σ and σ orbitals formed by the overlap of atomic s* orbitals. We also have σ(2p) and σ*(2p) orbitals formed by the end-on overlap of 2p orbitals. In alkanes such as ethane we can also have σ orbitals formed by the overlap of atomic s and sp³ atomic orbitals in C-H bonds.

What is molecular orbital symmetry?

A MO with σ symmetry results from the interaction of either two atomic s-orbitals or two atomic pz-orbitals. An MO will have σ-symmetry if the orbital is symmetric with respect to the axis joining the two nuclear centers, the internuclear axis.

What is atomic orbital class 11th?

Atomic orbitals are the 3-dimensional spaces around the nucleus where the probability of finding an electron is maximum. The molecules orbitals are formed by combining the atomic orbitals. In quantum chemistry we have encounter orbitals which are s, p, d and f subshells.

How molecular orbitals are formed?

When multiple atoms combine chemically into a molecule, the electrons’ locations are determined by the molecule as a whole, so the atomic orbitals combine to form molecular orbitals. The electrons from the constituent atoms occupy the molecular orbitals.
