Apply the rules / principles to fill the E.C. of homonuclear diatomic molecular ion. It includes Aufbau’s Principle, Pauli’s exclusion Principle & Hund’s rule of maximum multiplicity. What is electronic configuration of H2+ molecular ion H2+ has only 1 electron. It occupies the lowest energy level. E.C. for H2+ ion = sigma 1s1 Bond order […]

Molecular orbital are of 2 types that is sigma and pi. Here we will discuss how the different types of MO’s formed. What are the types of Molecular orbital 1. Overlapping of 1s with 1s MO The overlapping of 1s with 1s results in the formation of sigma 1s and sigma* 1s MOs 2. Overlapping […]

Formation of molecular orbital occur by the linear combination of atomic orbitals. Here we will discuss about the types of MO and their formation. What is LCAO Difference between bonding and antibonding molecular orbital Conditions for the combination of atomic orbitals to form MO Check out the post on Molecular orbital theory here : For […]

In molecular orbital theory, atomic orbitals combine to form molecular orbitals. Here, we will discuss the two types of MO formed due to LCAO method. What is molecular orbital theory Rules for filling electronic configuration of MO The rule states that electrons are filled in order of increasing energy. 2. Pauli’s Exclusion Principle A MO […]

Hybridisation determines the shape of molecule. The types of hybridisation depends upon the number and types of orbitals mixed together. Here, we will discuss the shape of molecules having bond pairs and lone pairs. What is Hybridisation Covalent bond is formed by the overlap of half filled orbitals. (hybridised or unhybridised) Shape of NH3 molecule […]

Hybridisation determines the shape of molecule. The types of hybridisation depends upon the number and types of orbitals mixed together. What is Hybridisation Covalent bond is formed by the overlap of half filled orbitals. (hybridised or unhybridised) Shape of BeF2 molecule on the basis of hybridisation Shape of BF3 molecule on the basis of hybridised […]

The shape of molecule is the particular arrangement of electron pairs around the central atom. VSEPR stands for valence shell electron pair repulsion theory. Shape of molecule containing bond pairs and lone pairs The regular shape of the molecule got distorted due to the presence of lone pair. The order of repulsion varies in this […]

The shape of molecule is the particular arrangement of electron pairs around the central atom. VSEPR stands for valence shell electron pair repulsion theory. Shape of molecule containing bond pairs only In BeF2 molecule, Be is surrounded by 2 bond pairs with 2 F atoms. Bond pairs repel each other at the maximum distance. This […]
